The Candle Sight-Reading Exercise for Peripheral Vision, Perceptual Span and Court Vision

The Candle Sight-Reading Exercise for Peripheral Vision, Perceptual Span and Court Vision


I have designed this exercise to stimulate musicians awareness of their peripheral vision and perceptual span.
Often times when faced with difficut musical passages, musicians fall into what is called 'tunnel vision mode' *. They loose their awareness of the whole and just focus on the immediate problem. However, as you know, a difficult measure or two move very fast when one is sight-reading.
This exercise is supposed to force you back into 'seeing the whole' and returning to a more broad view of the score.
I discuss peripheral vision, visual span and percetual span in several articles posted on this blog.
You can access the 'search' tool on the top of the blog to find all the definitions you will need.
I also have written about how sports psycologists have been doing a lot of research on this area, more than musicians do.
Today, I will post a link where you can read about  COURT VISION and video game players.
While reading it, you will find information about their preocupation with vision as well as a familiar subject explored on this blog when I describe the exercises on EyeQ Vision Therapy Program: Decision Making
while reading. (You can also search 'decision making' on this blog for more info)

* Tunnel Vision (Kalnienk Vision) is the loss of peripheral vision even though your central vision is fine.
I use the term tunnel vision here in a very loose way just to clarify this habit some musicians, athlets and video game players fall into.

Candle Sight-Reading Exercise

While practicing your sigh-reading, place two lit candles on each side of the keyboard (a grand piano is ideal for this). Make sure you are always aware of them (seeing them) while reading.
As you get better at this, try to add the awarennes of your hands moving below the score on the keyboard. This will amplify even more your vision field and it is somewhat easier since your hands are constantly moving.
Blow the candle :-)

Sight Reading Suggestion - Alexandre Dossin's edition of Tchaikovsky Album for the Young Ops 39

Schirmer Performance Editions ( Hal Leonard Piano Library) has published a wonderful edition of these beautiful works by Tchaikovsky. Pleasant to play and to read. In my opinion,  this edition is the best example of music printing  (typography)* one can get.  The page turns are well planned and the spacing between notes and staves are made so reading and counting is very easy.

Subvocalization, Text Reading X Sight Reading Music - Brainstorming

 
 The purpose of this article is to initiate a discussion about subvocalization and music reading. I have been researching this subject and will share some of its basic aspects here. Unable to find any research about subvocalization and music, all the articles I read about subvocalization were related to text reading only. Therefore, I am curious to hear your ideas and suggestions on this subject.
  I have been asking people about subvocalization for a few years now. One friend, a very fast reader, told me he rarely subvocalizes and was quite surprised to know that some people did. A Chinese friend told that she only subvocalizes when reading English, but never subvocalizes when reading Chinese. By doing so, she reads  Chinese much faster than she reads English. This friend also happens to be a very impressive music sight reader, which makes me wonder whether 'chunking music patterns' and 'chunking Chinese patterns' for her are one of the same.
I subvocalize 100% of the words I read, which may account for my slow reading speed.  Right now, I have been trying not to suppress subvocalization entirely, but instead to minimize this habit by avoiding subvocalization of small words or small expressions such as 'there are' or 'about' without losing comprehension. I found that my reading speed has already increased, leading me to speculate whether or not I am doing something related to subvocalization when reading music. If so, what is the impact of it on my sight-reading speed?
Do musicians 'inner sing' (I took the liberty to rename it to better reflect this action when reading music)?
 "O, learn to read what silent love hath writ! To hear with eyes belongs to love's fine wit." (Shakespeare, Sonnet XXIII)

"Subvocalization, or silent speech, is defined as the internal speech made when reading a word, thus allowing the reader to imagine the sound of the word as it is read. This is a natural process when reading and helps to reduce cognitive load and it helps the mind to access meanings to enable it to comprehend and remember what is read. Although some people associate subvocalization with moving one's lips, the actual term refers primarily to the movement of muscles associated with speaking, not the literal moving of lips. Most subvocalization is undetectable (without the aid of machines) even by the person doing the subvocalizing." (k12academics.com)

Language is processed in the left hemisphere of the brain while music is processed in the right hemisphere. However, music and language have many things in common. Both involve reading, comprehension, the auditory cortex, premotor cortex, and motor cortex to mention a few common traits.

"I learned to speed-read and read War and Peace in an afternoon. It's about Russia" (Woody Allen)


While reading about subvocalization I encountered many speed-reading courses based on poor research that advocate the increase of reading speed rate by total suppression of subvocalization. Such techniques vary, with suggestions that range from while reading, one should listening to music, count out loud or hum, use a pencil to push the tongue down in order to immobilize it, chew gum, tape one's mouth,  to holding one’s jaw. A few speed-reading courses however, seek only to minimize subvocalization. The reason behind this is that while subvocalizing we can only read at the speed we can speak. "The silent reading speed for 12th graders when reading for meaning is 250 words per minute, whereas the speed for oral reading is only 150 words per minute” (Carver, 1990).
"It may be impossible to totally eliminate Subvocalization because people learn to read by associating the sight of words with their spoken sounds. Sound associations for words are indelibly imprinted on the nervous system—even of deaf people, since they will have associated the word with the mechanism for causing the sound or a sign in a particular sign language. Subvocalizing is an inherent part of reading and understanding a word, and micro-muscle tests suggest that subvocalizing is impossible to eliminate. Attempting to stop subvocalizing is potentially harmful to comprehension, learning, and memory. At the more powerful reading rates (100-300 words per minute), subvocalizing can be used to improve comprehension." (k12academics.com)

Subvocalization, as well as reading out loud, can improve memory and comprehension because the reader adds another sensory modality (auditory cortex) to the visual aspect of reading.

Here is a section from an article by Chris Parnin (College of Computing Georgia Institute of technology) I found very interesting:


           Subvocalization - Toward Hearing the Inner thoughts of Developers

A. Inner Speech
Inner speech is soundless mental speech that accompanies
and carries our inner thoughts. During silent reading of
text, we often perceive the sound of partial or complete
words we encounter but make no perceivable movement of
our lips or sound. However, silent reading is a relatively
recent human invention: reading during medieval periods
was primarily spoken aloud or in muffled tones [2]. One
of the first accounts of silent reading occurs in 397 A.D.
when Saint Augustine reports his astonishment of seeing
his teacher, Ambrose, reading to himself [3]:
Now, as he read, his eyes glanced over the pages
and his heart searched out the sense, but his voice
and tongue were silent.
But what has been understandably called silent is not
necessarily so. Even for modern readers, ever so slight
movement of the tongue or lips (imperceivable to the naked
eye) still occurs when we read or perform mental calcula-
tions. Movement of vocal muscles itself is not necessary for
thought, but merely the final recipient of motor and premotor
commands sent by the brain. Dodge (1896) demonstrated
this when he anesthetized his own lips and tongue and found
no effect on his own inner speech [4].
Inner speech is not a perfect mirror of speech: when
subjects read a novel aloud, the reading speed was 66%
slower than silent reading [5]. Often a reader may only
subvocalize the first part of the word.
Other late 19th and early 20th century researchers at-
tempted to understand motor movements associated with
cognition [6]. Some attempts used a glass balloon that en-
cased the tongue to detect movement, whereas others used an
inflated balloon to immobilize tongue movement. Ultimately,
movement of the mouth or tongue was found to be unreliable
as too much noise resulted from breathing. More success
was found with readings from electromyographs (EMG) that
recorded electricity from muscle nerves.

Sight Reading Children's Songs 11-20 by Chick Corea

"Some people ask: “Are we going to some sort of children's concert? Some new compositions for children?” Whenever I can, I try to explain: this is children's music in about to the same extent as “Alice in the Wonderland” by Caroll Lewis is children's literature. Youngsters and adults enjoy reading them alike, don't they. They appreciate its simplicity, playfulness, sense for nonsense, but in particular – they return to the almost forgotten territory of a child's soul that they rediscover by way of words and paper." (http://quakvarteto.cz/en/childrens_songs)
                        About Sight Reading Them

Sight reading Children's Songs 11-20 is a lot more challenging than sight reading 1-10. I would place these pieces at an intermediate conservatory (private studio) level. These compositions require technical and emotional maturity form the performer. They are a lesson in form and atmosphere changes.
Nos. 11-20 explore the keyboard even more than the prior ten pieces. They explore leger notes, chromaticism and rhythms become increasingly harder to read though once again, the metronome markings help students make sense of them. Obstinati bass is not as frequently as before.
No.14, in particular, would be a resourceful piece to learn how to read or 'see' common tones between chords. There is much more information from the composer such as pedal markings, dynamics and articulations.
No.18 is great for teaching how to take advantage of the accompaniment (which switches from one hand to the other) as a tool for counting, and how by minimizing counting one can match the melody into it.
Nos.17 and 19 once again betray melodic* expectations imposing a bigger challenge to sight readers so they cannot predict what is coming next.
No.20 (short notes- brisk and light) is a fast and playful piece with hard accents and provocative rhythms.

       * Expectations, Previous Experiences and Sight Reading

According to Lehman and Erichson (1996), our expectations are powerful. Expectations along with our previous knowledge are a big part of completing the score during sight reading. Therefore our previous knowledge of harmony, style and even music history, next to our experience (amount of sight reading, accompaniment and chamber music practice, ear training, and exposure to repertoire by listening or playing) are important tools for sight reading successfully. Research also shows that both text readers and music readers often perform automatic corrections in a suitable style and context when there are misprints without being aware of it based on expectations and experience alone.
According to my experience as a musician, modern and atonal music are harder to sight read because they betray our expectations. There are no familiar rhythmic, harmonic and melodic patterns.
In a similar study by Wolf, chess players experience the same problems when faced with random combinations on the chess board.
Visual closure exercises use expectations and previous experiences. See http://sightreadingpianomusic.blogspot.com/2010/05/exercise-viii-visual-closure-auditory.html 

                                                      
               Expectations also impact the audiences!

"The sadistic newness of The Rite's (Rite of Spring by Stravinsky) patterns, its stubborn refusal to conform to our learned expectations, is the dirty secret of its discontent. By disobeying every rule we think we know, Stravinsky forces us to confront the fact that we have expectations, that the mind anticipates certain types of order, followed by certain types of release. But in The Rite, these expectations are rendered useless. We do not know what note will come next. And this makes us angry." Proust is a Neuroscientist by Jonah Lehrer

Sight Reading Children's Songs by Chick Corea 1-10

Chick Corea started writing Children's Songs in 1971. They were recorded by him in 1983 and released in 1984 (lable EMC). Length 36:14
 His work has been compared to Bartok's Mikrokosmos because of its use of pentatonic scales, its variety of moods, cross-rhythms and increased challenges. I am not a fan of such comparisons but it is a helpful way to draw a picture of this composition to teachers who don't know it yet. I read an absurd parallel of these pieces with Ligeti's studies which made my hair raise. If I were to compare them with any work, it would be to Robert Starer's "At Home Alone." Starer wrote it around the same time, in 1980 and dedicated them to "...people who play the piano when they are at home alone. This does not mean that they cannot be played for others, in private or in public; of course they can. It only means that the images, views, sounds and thoughts will come, as they did to me, when you are at home alone." (Starer) I had a similar feeling when I read through Corea's songs. Same combination of modern, erudite and jazz languages. Corea's composition gave me this sensation that everyone would love to play Children's Songs at home alone...
About his work, Corea wrote:"The Children's Songs are the first collection I've written specifically for solo keyboard. I wrote the first song in 1971 to convey simplicity as beauty, as represented in the spirit of a child. Songs 1 through 15 were composed for Fender Rhodes and 16 through 20 for the acoustic piano, although any of the songs can be played on either instrument. Songs 17 through 20 were composed during a one month period in 1980, completing the series. The songs lend themselves nicely to various forms of expansion with orchestration." (Chick Corea)
 This composition provides the teachers with an opportunity to not only teach sight reading but to teach form as well.

                             About Sight Reading Them

 No. 1 
Time Signature 6/8.  My favorite time signature to practice sight reading because it always provides   the student with opportunities to look ahead.
Here Corea uses obstinati accompaniment and builds a dreamy atmosphere as if the child is still asleep and will gently be awaken through the set.
Both hands 'read' in contrary motion.

No.2
Pay attention to how well Corea writes the metronome markings helping the student to embody the sophisticated rhythms.
Hands 'read' in parallel motion.
Very comfortable and pianistic writing.
Once again, long notes give the student time to predict and prepare ahead.
The last 7 measures are helpful for visualizing the differences between 6ths and 5ths.

 No.3
Time signature 6/8.
Two voices on the LH.
Obstinati accompaniment again making reading pleasant.
Wonderful example of conveying a message in just under a minute. Less is indeed More.
I love how these pieces don't finish. They just stop!

 No.4 
Time signature 6/8 and obstinati accompaniment. Here the obstinati bass counts for the student so concentration can be entirely focused on reading.
Good exercise in reading melodic and harmonic 6ths.

 No. 5 
Interesting rhythm alternating between hands.
The half notes at the beginning of each measure allows the student to prepare the next chord and   accidentals.
Helpful time signature and metronome marking instructions.
Rich articulation.

 No.6 
 Two sharps.
 First opportunity for both RH and LH to read the treble clef.
 Obstinati accompaniment.
 Time signature 3/4 but played "in one" thus giving you the same 6/8 feeling.
 Use of appogggiaturas.

 No.7 
 One sharp.
 6/8
 Obstinati accompaniment.
 5ths on the RH.
 Easy to read.
 Chromatic but accidentals are always preceded by long notes so there is time to look ahead.

 No.8
 4/4
 LH and RH can read treble clef.
 Highly chromatic.
 Exercises four voices.
 Rich dynamic markings.
 Technically this is the most challenging so far with plenty of opportunities to scan the score due to  the frequent use of half notes.

 No.9 
 2/4
 Two sharps.
 Rich articulation in both hands.
 Nice jazz flavor.

 No.10
 LH rhythms help with counting.
 Very challenging because the melody is unpredictable and betray our expectations (I talk about this   in earlier posts). Previous experiences and expectations are very helpful for sight readers. Having no expectations is a challenge and one has to work much harder.

EyeQ - Reading and Processing Information - How it helped my Sight-Reading

My optometrist suggested that I try the EyeQ (vision therapy) program since it has been some time since I finished working on PTSII. I decided to spend a couple of months working on it and stop the practice of sight-reading just to see if I would be able to transfer the therapy alone to my sight-reading. As you know, while I worked on PTSII, I practiced sight-reading everyday.
At first, I didn't think EyeQ was going to help me because it is much more focused on text reading. However, to my surprise, I again experienced incredible improvements even without my daily practice. The exercises are not half as interesting as the ones on PTSII, but I benefited a lot from the fast pace: it improved my reaction time and information processing, expanded my peripheral vision, and I benefited a lot from the exercises where the eyes have to follow objects horizontally, vertically, and diagonally.
EyeQ trains your eyes and brain to work together more effectively. According to other people who went through this program, improving eye-brain processing showed improvements not only on text reading, but sports, music, and typing abilities.
The program was developed by Dr. Akihiro Kowamura in the 80s. Today, it is widely used in Japanese schools. According to the manual, our reading abilities are impaired by narrow field of vision, sub-vocalization* and weak eye muscles. (EyeQ exercises six sets of eye muscles).
There are 12 exercise sessions (7 minutes long) and three levels according to your age. Each session starts and ends with a reading speed test. Typically, there are 3 stages: warm up exercises which are designed to strength the muscles and expand you visual field, super fast exercises, and finally the speed of the exercises drops to a moderate pace.

There is a Personal Training Center where you can design your own therapy which includes:
- Eye Exercises: horizontal, vertical, and diagonal saccades and expanding circles and squares to improve peripheral vision.
- Maze Games: your eyes have to solve mazes in order to activate the right brain and scanning abilities.
- Number Finding Games: improves scanning abilities. (After a lot of training, I was able to see the whole page at once. It is remarkable.)
- Two Point Training: it is supposed to be one of the most effective ways to improve reading. In this exercise, each line begins and ends with a square and you have to move your eyes as fast as possible from the left square to the right without reading the words. I would like to hear form a person who has succeeded in doing this exercise. To me, it remains impossible to achieve the goal unless you have bionic eyes.
- Comprehension Test: you can choose a short piece to read and be tested by answering 10 questions about the text.

Tracking Progress:
Your progress is automatically recorded in a chart.

A poster with a case report about my results after vision therapy is going to be presented by Dr Jeniffer Simonson at the 2011 COVD meeting this coming October.

*I confess I am still not able to break the sub-vocalization habits.

Sight-Reading and Rhythm - Intermediate Repertoire

"I have benefited a lot from your suggestions of repertoire. Could you please suggest some SR material (intermediate)that explores diversity in rhythms?"

Upon receiving the e-mail above, the first thing that came to my mind was a rarely performed set of 10 pieces by Villa-Lobos: Francette et Pia. This set was written in 1929 for the piano class of the celebrated Marguerite Long. This suite mixes Brazilian and French songs and tells the story of a little Brazilian Indian boy (Pia)* and a French girl (Francette). I can't help imagining a recital alternating a boy and a girl performing these solo pieces and at the end, the two kids closing the recital with the final piece called "Francette and Pia Play Together Forever" (it is a duet - 4 hands).
Mixed with the Brazilian folk and indigenous melodies, you will recognize the French national anthem (Marseillaise - #8), Au Clair de la Lune (#1), Le Bon Roi Dogobert (#2) and Malbrouk S'en Va-t-en Guerre (#6).
As expected, Villa-Lobos writes challenging rhythms, but the repetitive patterns through the compositions make this set a good source for sight-reading (there are lots of opportunities for self-correction). Each piece is rich in tempo, meter and key signature changes.

1 - Pia Came to France.. (it opens with an Indian theme).
2 - Pia Saw Francette...
3 - Pia Spoke to Francette...
4 - Pia and Francette Play Together...
5 - Francette is Angry... (the edition I have translates this piece as Francette is sorry, however, the right translation is Francette is angry).
6 - Pia Went to War... (the composer writes "to make kids used to syncopation and exaggerated accents").
7 - Francette is Sad... (it opens with a Brazilian March followed by a French theme).
8 - Pia Returns Form the War...
9 - Francette is Happy... (the composer brings back a variation of previous themes).
10- Francette and Pia Play Together Forever... Four-Hand Duet

Villa-Lobos dedicated a lot of time writing pedagogical music exploring Brazilian children's folk tunes. My favorite set is the Cirandinhas (it is extraordinary!). There is also Guia Pratico (11 sets of 6 pieces in each), Carnaval das Criancas Brasileiras, The 3 Marias, Petizada, The Broken Little Music Box, and The Toy Wheel.

* Pia means a little boy of Indian descent. In Tupi-Guarany, it is an expression of affection like "dear boy". Today in Rio Grande do Sul (south Brazil), we call all boys "pia".
Guarany is an indigenous language in South America.

The Role of Cognitive Skills and Sight-Reading

A few months ago, I bumped into an article that explored my main concerns about research on sight-reading. The author Ji In Lee opens the article stating that there is no feasible theory behind sight-reading and that until now, no one has explained differences between individuals in SR achievements.
The article “The Role of Working Memory and Short-Term Memory in Sight Reading” (Ji In Lee, 2003) focuses on the information processing elements needed for sight-reading. That is, Lee studies the role of working memory (WM), short-term memory (STM) and mental speed and how these 3 elements could be valuable predictors of sight-reading. If you have been following this blog, you are going to find such elements familiar to you. The vision therapy exercises I have been analyzing (PTSII) work on the oculomotor skills* as well as information processing. After you see an image, information is sent directly to your brain in order to be processed, hence the eye’s nickname, “the outside brain.”
The conclusions of this study are that "sight-reading skills should be explained within the framework of general cognitive skills and that WM** and speed of processing*** are significant predictors for sight-reading achievements.”
STM however did not show a high significance in explaining sight-reading differences. It makes sense for WM to have a more important role since while musicians read, they have to store information seeing ahead as well as process it in terms of how to finger it, chunk it, phrase it, etc. During the mechanical output of a passage seeing in the recent past, we are already working (processing) on what is coming ahead.

There is very little research done on the role of information processing and sight-reading:
- Lee (2003) has demonstrated that SR should be explained within the framework of general cognitive skills. WM, STM and mental speed are significant predictors for SR achievement.
- Berz (1995) designed the first model of WM based on Baddeley’s (1990) model, which include a music memory loop.
- Kopiez and Lee (2006) have studied general cognitive skills (WM), elementary cognitive skill (RT), expertise-related skills (experience and ear training/auditory expectancy).
- Engle (2002). http://cdp.sagepub.com/content/11/1/19.short (abstract)
- Lehmann and Ericsson (1993) have tested STM in good and poor sight-readers

* Ocular Motility: Visual Search, Visual Sequencing, Visual Sequential Processing and Visual Scan.
** WM: Tachistoscope Exercise, Visual Span,Visual-Visual Integration.
STM: Visual Concentration.
***All PTSII exercises focus on developing Information Processing, Temporal Vision Processing and Rapid Automatized Naming.

Can I Have Your Divided Attention? Attention and Sight-Reading

According to the book Cognitive Psychology by Sternberg, divided attention is the attempt to handle more than one task at once. Sounds familiar? Sight-reading music requires all musicians to handle several tasks all the time. Pianists suffer even more with the fact that they have to read two different clefs.

Example:


During performance, we attend to more than one automatized task at one time. This is supposed to be easier than attending to more than one controlled task at a time which is the case when sight-reading. While sigh-reading there is a great deal of decision making, problem solving, comprehension and muscle control. The good news is "...with practice, individuals appear to be capable of handling more than one controlled task at a time, even engaging in tasks requiring comprehension and decision making". (Sternberg)
When sight-reading piano, besides reading two distinct clefs, we also have to execute two distinct articulation, phrasing and dynamics. If you are sight-reading a fugue, for example, you can face more than that. Add pedal markings to that, and you might need a drink.

Example:


Marlos Nobre "Caboclinha"


Attention is all the information an individual manipulates. Because our working memory has limited capacity (7 +2/-2 items or chunks), attention allows us to use our cognition resources judiciously to respond fast and accurately to interesting stimuli and to remember salient information. Consciousness, on the other hand, is only the narrow range of information that the individual is aware of manipulating. It allow us to monitor our interactions with the environment to link experiences and expectations while planning future actions.(Sternberg)
One can see how both attention and consciousness play an important role in sight-reading. Attention relates to our first encounter with a musical passage and to how we select salient information to be played. While consciousness, takes this information selected and infers our previous experiences and expectations in order to plan our final output.

Typography and Sight-Reading Music

Example I: observe how large the space between treble and bass clef on the same staff are; how close the treble and bass clefs from different staffs are; how one and a half beats are connected and how beats are not connected.



Example II Big Note Score: lots of glare; difficult to read globally (by chunks)


Example III: look how badly the rests are written.



"Typography is the style and appearance of printed matter."

From the point of view of visual research, "comprehension and information processing derived from the printed word can be greatly influenced be typographical presentation. Legibility research is concerned with the efficiency of information transmissibility of the printed word." (The Ergonomics of Reading - Long,R. Garzia, Wingert ,S. Garzia - 1996) One can say the same thing is true for the printed music. How often have you bumped into a confusing edition or "disorganized" printing that only makes sight-reading frustrating and stressful?
Research has been measuring eye movement patterns to determine variations in reading speed from one typographical style to another.(Tinker, 1949) Such variations range from the duration and number of fixations to number of regressions. According to Ralph Garzia, an increase in any of these parameters strongly suggests that the reader is experiencing difficulty. Garzia also explains why (text reading) serif typefaces have superior results in terms of word legibility. He states "Serifs link the letters together to form word units...They help to maintain adequate spacing between letters and emphasize the separation between words...They help to avoid confusion by enhancing letter differentiation." If you read what he states carefully, you can easily relate it to music. Musicians often struggle to read vocal lines because the beats are not connect in units or when the spacing between beats are disproportional.
In cognitive psychology, this is called "context effect." It occurs when the surrounding environment influences perception of patterns and forms. "The strength of the context plays a role in the object recognition."(Bar, 2004)
One context effect theory called "Configurational-Superiority Effect" (Bar, 2004 and Pomerantz, 1981) establishes that objects presented in certain configurations are easier to recognize than objects presented in isolation, even if the objects in the configurations are more complex than those in isolation. People perceive differences faster when objects are integrated configurations comprising multiple lines than they do isolated lines.
Example I
The amount of space between lines is also an issue.
Example II
The type size is an inverse U-shaped curve. "Smaller and larger type sizes cause reductions in reading rate."
I have observed this problem with students every time I used those "BIG NOTES" scores. Even I feel perplexed by the exaggerated sizes and spaces between lines. Garzia states that too much space is also undesirable for legibility because the added white spaces are a glare source and the oculomotor control system may add difficulty finding the beginning of the next line resulting in rereading and skipping lines.
The Global Precedent Effect Theory* (Navon, 1977)shows that people can respond and identify small letters positioned close together in a "global" way (chunks) faster then in a local way. When letters are more widely spaced, the Local-Precedent Effect Theory* leads people to identify letters in a local way (note by note) faster than globally. In another words, it is quicker to id local features when letters are widely spaced (note-by-note) and quicker to globally (chunks)id notes when they are close together.
Example III

I strongly recommend that you read this article "The ergonomics of reading". It has a lot of information about types of ink, paper, color X black ink, margin sizes and even reading mathematical symbols.

Curiosity: "Italic type slows reading by 15 words per minute. This was found to be consistent with the subjective impressions of 96% of readers studied." (Garzia)

Sight-Reading Robert Starer - Game With Names, Notes and Numbers

Game With Names, Notes and Numbers (1979)

These wonderful 12 pieces are perfect for beginner students to sight-read. They are very descriptive, game-like pieces that facilitate sight-reading and information processing.
Starer writes: "These pieces move from the easy to more complex. They are, like all games, quite serious. Each of them can be studied by itself."
All these pieces are carefully fingered, phrased (a rare quality for beginner pieces), pedaled and provide rich articulations as well as dynamic markings.

1- ABE, GABE, ADA, FAE and ED "is a game with names. All the notes in this piece (the letter-names of the notes) make up the five names in the title". (Starer)

2- In the Mirror "what each hand plays is a mirror image of the other". (Starer)

3- Echo Chamber "if the sustaining pedal is kept down as indicated, the resonating effect should come by itself". (Starer) Good way to work on ties.

4- Turn-me-Around "is a game for the eyes, a game for people who like puzzles. 'Madam I'm Adam' can be read backwards; this piece can be played upside down as well". (Starer)
This is one of my favorites. It has a great effect as a recital piece. The student is not required to play it by memory. I usually have them performing it twice where the second time around, they turn the score upside down. Very cool! The audience love it.
I also like how the hands are not locked on a particular hand-position and they only move a step at a time.

5- Countdown "as the numbers are called out, each bar has one beat less then the one before". (Starer) The first measure has nine beats, the second has eight, and the student plays all the way down to one beat. The phrasing is unique. The first measure has 3/3/2/1 note-phrase, the second has 2/2/2/2 note-phrase, then 3/2/2, 2/2/2/, 2/2/2/, 23/2/, 2/2/, 3, 2 1. There are 3 optional endings.

6- Evens and Odds "refers to the number of beats per measure in 3, 4, 5 and 6 times". (Starer) It has a cool pop-sounding rhythm. Students like it a lot.

7- Up and Down, Right and Left, Over and Across "asks you to find fingers on the same notes and to cross hands". (Starer) It is a reasonable way to sight-read repeated notes and it is also good for "interval reading".

8- Darkness and Light "is a game with sounds. It contrasts low with high, threatening sounds with pleasing sounds, dissonance with consonance". (Starer) It is a good opportunity to point out musical sequences to students.

9- Adding and Taking Away "notes are added to form 'clusters' and then taken away, one by one, to return to a single note". (Starer) This is done with both hands.

10- Walking With Two Fingers "is for people who enjoys walking with 2 fingers on table-tops or desks". (Starer) The fingers are always 2 and 3. I like it because it explores a wide range of the keyboard. The rhythm is fun and the two fingers chosen, play harmonic seconds as well as melodic seconds throughout the piece.

11- Sliding into the Keys "takes a tune, or a chord, to many different keys without what is called modulation." (Starer) It has rich dynamic markings. the 6/8 measure and the rhythm resembles. the "Pop-Time" form "At Home Alone".

12- Twelve Notes Twelve Times "presents 12 different ways of presenting all the 12 notes: in 4ths, 5ths, the chromatic and the whole-tone scale, and in chords". (Starer) The 12 ways are numbered in order to make it more clear to the students. Every thing on this piece is explored: dynamics, phrasing, imagination, pedal. In the middle of this piece, there is a cool sequence of "jazzy" chords.

Next, I will write about At Home Alone, Sketches in Colors I and II, Four Seasonal Pieces, and Seven Vignettes.
All these pieces and more can be found on the book Piano Solos-Robert Starer-Album for Piano (MCA Music Publishing.-Hal Leonard)

Procedures for Sight-Reading (PTSII)

PTS II is a computer program available only through your optometrist. It is installed in your home computer. There are 11 exercises to work on and you advance levels only if you meet the requirements. (I have been describing my experiences with each exercise on this blog)

PTSII procedures for sight-reading are:

-Speed of information processing;
-Perceptual span;
-Peripheral Vision;
-Visual attention;
-Visual memory;
-Ocular motility.

All 11 exercises enhance these skills.

How Musicians Process Information



In our everyday activities, all of us learn and process information either simultaneously or sequentially. This perceptual-cognitive theory was developed by Alexander Luria (1966) and later expanded by Das (1979) and Naglieri and Das (1997).
When musicians look at a triad they quickly recognize its shape and its inversion (spatial configuration). They see it as a whole, all at once. This is an example of processing information simultaneously. In order to spell such triad (and scales), musicians have to use their sequential processing skills (linear approach).
The speed of information processing skills is an essential component to learning and reading and can be improved by doing the appropriate exercises. “It can be shown that increases in processing speed are linked to increases in other cognitive domains, which include sight-reading” (PTS II Documentation and sight-reading).


According to the authors, the exercises presented on the PTS II program are designed to enhance Information Processing Skills, Temporal Visual Processing skills and Rapid Automatized Naming skills.

Information Processing Skills is the ability our brain has to recognize, understand, stores and responds to information collected by our five senses. (article)

Temporal Visual Processing (TVP) is the means by which musicians process brief short stimuli and rapid sequences of information during sight-reading. TVP is responsible for the manner musicians make choices and prioritize information. Such choices vary from identifying and individualizing single notes to perceiving large stimuli presented in sequences such as chords, scales, accompaniment styles, arpeggios, etc. TVP also controls the musician’s capacity to change fixations form note-to-note, beat-to-beat, and so on. Improvements on this area result in more fluency and better comprehension. Even a small deficit on TVP can compromise reading ability, can cause loss of place while reading, visual fatigue, slow reading speed, symbols overlapping, lack of comprehension and frustration. (PTS II)

Rapid Automatized Naming (RAN) is the ability to recognize and name harmony, notes, accompaniment patterns, sequences and rhythms in a fast an accurate way.

A Second "Look" at the Tachistoscopic Exercise and Reading Music


Tachistoscopic perception is the capacity to identify and reproduce a visual stimulus presented rapidly, usually faster than 1/25 of a second. It is used chiefly to assess visual perception, memory or to increase reading speed. Tachistoscopic perception requires Perceptual Speed, Visual Memory, Visualization and Temporal Visual Processing.
This exercises is recommended for reading fast music. It spans the visual field and problem solving. One has opportunity to group fast stimulus into chunks. It develops working memory by adding a distractor before you enter your answer. The purpose of the distractors is to retain certain information while simultaneously processing the other task.

Tachistoscopic Exercises for Musicians

Although tachistoscopic ability is a very important skill for all readers, exercising this ability alone does not guaranty improvements on your sight-reading. In fact, experiments with tach practice for musicians by using musical examples had unimpressive results.
I found a reasonable explanation for such results on an article called “Eye Movements in Reading: Facts and Fallacies” by Stanford E. Taylor. He reports:"No studies to date have shown that training to widen span has resulted in the ability to see in phrases during continuous reading. Feinberg's study (1949) suggested that physiological limitations of the eye will probably prevent readers from ever reaching this goal. It is rather startling to note that despite the findings of over a hundred studies of eye movements, writers of reading improvement texts have persisted in this misconception. Perhaps they have done so because they know a person can see 3 or 4 words when STARING at a print or when words are flashed TACHISTOSCOPICALLY. This is possible because the seeing situation is STATIC, allowing time to assimilate the less distinct impressions that occur in the periphery. The situation is in direct contrast to that encountered during reading, when retinal impressions are superimposed on preceding ones at the rate of 3 to 5 per second in a DYNAMIC act where the kinesthesia of the ocular activity and the sequence of impressions further reduce the already tenuous peripheral impressions. In addition, there is the demand for continuously ORGANIZING the MULTIPLE IDEAS presented in reading material. Consequently, the span of recognition in reading is distinctly smaller than that occurring and measured in STATIC seeing situations and may be thought of as "salvage" span. "


Musicians in order to improve their sight-reading abilities need more then just tach exercises because seeing a stationary target is different then seeing dynamic ones
K.L. Bean(1938)has researched and tested musicians doing tach exercises by using musical samples. His results are mentioned in detail on a paper called "A Cognitive Model of Musical Sight-Reading" by Thomas Wolf (1976). Here is the conclusion about musicians practicing tach alone: ” While there was some improvement, the results were generally unimpressive. Only 25% of the subjects improved significantly in both speed and accuracy of reading."
Wolf goes on reporting that “To get to the heart of this matter, we must worry less about what musicians see on the page and devote more attention to the cognitive processing which allows him to transfer the visual image into muscular act.”

This option by Wolf is what researchers call "information processing skills" or "problem solving". I wrote about problem solving on my previous entry.


The best tach exercise I found so far is the one on the PTS II program. I will describe them and post my results once again. I have not yet found a tach exercise for musicias. However, it really DOES NOT matter how you exercise this skill. Once your eyes learn a skill, they will apply it everywhere despite the target you are using. (This is the focus of a lecture I am giving for the MTNA Conference in March 2011 - Milwaukee).
Last night I reader e mailed me about suggesting some tach exercises. There is good exercise on a site called "Tachistoscope-Electronic Literature Collection"*
Another option is the PTS II which you need to acquire through a developmental optometrist. - If you know some tach exercises for musicians, we would love for you to share with us.
I am currently trying a program called EyeQ which although very good, has a brief and very simple tach exercise. There is a program called Eagle Eye available on the Luminosity.com site. I have not seeing it yet. But their exercises are usually great.
I will work and report on the Eagle Eye in the future.

Curiosity: Measuring perceptual span by using tach tests( performed by Weaver, 1943), produces an overestimate because musicians are able to guess some notes (Wolf,1997).

The Problem of Problem Solving in Sight-Reading

Along with short-term memory, our capacity to solve problems is crucial to for sight-reading. It involves very sophisticated perceptual and cognitive abilities. Given that we cannot read all the notes on the score while sight-reading, we must sometimes:
- Leave out “unnecessary” notes.
- Complete or even “guess” musical passages.
- Make instant decisions about fingering, articulation, phrasing, harmony, etc.
- Make rapid decisions about where and how to look at chords and different compositional styles such as polyphonic and homophonic writings.
- Combine long musical passages into chunks (e.g., scales, arpeggios, accompaniment patterns, melodic sequences).

Garzia (Vision and Reading,1996) says, that decision making refers to visual cognitive style and there is a continuum decision making while reading that requires a reflective and thoughtful problem solver.

PTS II offers several exercises that enhance working memory and problem solving skills.

Exercise X - Visual Sequential Processing or "Eyes out of Orbit"



According to the PTS II manual, Visual Sequential Processing develops the ability to identify and count a specific stimulus that is repeated in a sequence of different stimuli. Visual Sequential Processing requires Temporal Visual Processing, Perceptual Speed, Visual Attention, Visual Concentration and Saccadic Fixation.

You have to count the number of times a specified stimulus appears in sequence of stimuli. The target flashes inside of a box and then a series of letters, numbers or pictures will be flashed on the screen.

Variables:

There are four types of stimuli: Pictures(very difficult because they are somehow stylized and not very clear), Upper Case Letters, Lower Case Letters, Numbers
Stimuli Size: Medium and Large.
Speed of Stimuli: there are seven speeds ranging from slow to fast.
Number of Stimuli: it varies from 20 to 60 stimuli.
Stimuli Placement Patterns: there are six progressive placement patterns utilized.

The patterns could have a fixed or a random presentation.
In the fixed presentation, the stimuli will be presented in a fixed order and location. In the random presentation, the location of the stimuli in the sequence within a level will be randomized: it could show up on random places on the screen.
At this point, the speed is very fast. Hold on to your eye balls her or they go out of the orbit :o

It improves concentration, attention and saccadic fixation and speed. Good exercise for fast music.

Eye-Hand/Voice Span and Perceptual Span

Eye-Hand/Voice Span: measures how far ahead the eyes are from the hand/voice

Skilled readers Less skilled readers

4 notes 2 notes (Furneaux and Land)
about 2 beats under one beat (Truit at al.)
2 beats 0.5 beat (Rayner and Pollatsek)
1-2 notes 1-2 notes (Weaver) (more complex music)
4 beats (singers- Goolsby, 1994)
0 up to 2 notes (Jacobsen, 1941)


(I think it is more effective to measure EHS in beats because of the “chunking” abilities of the musicians-one beat can include several notes).

All researchers agree that the EHS of the musicians is small.
Truitt at al conclude that musicians do not need to see more then one measure ahead of the hands/voice in order to read well and readers rarely extract information beyond a measure (4 beats). However small, that does not mean that the visual process of the music is not ahead of the fixation (Weaver, 1943; Goolsby, 1994; Kinsler and Carpenter, 1995).
Rayner and Pollatsek state: “This discrepancy between the data and conventional wisdom might be due to the fact that musicians, like all human perceivers, are seduced by the illusion that information can be extracted from a wider region of vision than is actually possible”. (1997)


Perceptual Span: it measures the size of the visual field and our awareness of it. The perceptual span is the region around the fixation in which we obtain some information.

Both Truit at al and Rayner and Pollatsek (1997) found that, contrary to the musicians believes, the perceptual span is also small (the visual processing is also close to the hands). Its size is more or less one measure. That is > 2 < 4 notes ahead of the hands. Visual processing for musicians is also comparable to reading aloud (1.1 words for adults and less then half a word for a 1st grader-Garzia) and typing (about 6 characters-Rayner and Pollatsek).
(When researchers measure the EHS, they are taking the average and when they measure the perceptual span, they take the maximum).


Rayner and Pollatsek concluded that the less skilled reader when combining the EHS and the PS, extract useful information up to about 3 or 4 beats ahead of the hands. For skilled readers, the combination leads to only up to 5 beats ahead of the hands.

In the article Eye Movements in Reading: Facts and Fallacies by Stanford E. Taylor, he estates that “No studies to date have shown that training to widen span has resulted in the ability to see in phrases during continuous reading. Feinberg’s study (1949) suggested that the physiological limitations of the eye will probably present readers from ever reaching this goal “… when retinal impressions are superimposed on preceding ones at the rate of 3 to 5 per second in a dynamic act where the kinesthesia of the ocular activity and the sequence of impressions further reduce the already rather tenuous peripheral impressions. In addition, there is the demand for continually organizing the multiple ideas presented in reading material. Consequently, the span of recognition in reading is distinctly smaller than that occurring and measured in static seeing situations (Taylor, 1957) and maybe thought of as “salvageable” span”.

Exercise IX - Visual Concentration


Visual Concentration according to the PTS II Manual is the ability to remember the location of pairs of targets that are hidden on various sized grids. This exercise requires visual spatial memory, spatial visualization, visual-motor accuracy, and simultaneous processing.
This exercise also helps the musicians to develop working memory and problem solving.

This traditional grid memory game is played against the computer.

Variables:
- Grid Size - number of boxes in the grid. It varies from six to forty boxes.
- Skill level of the computer opponent – average or above average.
- Targets – there are five targets. Pictures, upper case letters, lower case letters, numbers and symbols.

Goal:
The goal in order to advance levels is winning or tying 70% of the time.

Short Term Memory and Working Memory

Working Memory is the ability to retain information in our short-term memory (in our "buffers") while simultaneously processing other material.
The ability to transform a complex input into mechanical results is directly related to this kind of memory. However, short-term memory is never addressed in music lessons. Teachers only focus on the long-term memory, which is the kind of memory used on performances.
During s-r, it is actually good to have a small Eye Hand Span and a small Perceptual Span* because if the input is to far from the mechanical output, we run the risk of loosing the material read. Psychologists say that the brain (buffers) only process 7 chunks at a time.
Our buffers also have the purpose of rearranging information and “solve problems” (i.e., fingering)

Take a look at a study by Simon and Chase, 1973 that discusses the buffers of chess players which are similar to the musicians’ buffers).

Working memory and Short Term Memory are vital skills needed for s-r and easily improved with exercises.
The PTS II addresses short term memory and working memory on the following exercises: "Visual Concentration", Visual Span" and the "Tachistoscope".
Both Visual Span and Tachistoscope use distractors. The purpose of the distractors is to retain one information while simultaneously processing other task.

*I will discuss this subject of small eye hand span and perceptual span on my next post.
