Human Data Compression

Yesterday, I attended a rehearsal with the Grease band, where in addition to the songs we have known for many months, we were to learn about a half-dozen songs very rapidly. One of the songs is "Time Warp" from the Rocky Horror Show.

I was a little jealous when I was not asked to participate in the local production of the Rocky Horror Show, but I imagine that some day, I will have my chance to play Dr. Frankenfurter. Unfortunately, my longing to participate in the Rocky Horror Show has nothing to do with this post, so once again, I must put a topic on the back-burner -- to be forgotten until the desire resurfaces.

At last evening's rehearsal, the bandleader played a recording of the Time Warp for the band members, in order to get an idea on the key, riffs, and overall structure of the song. As I sat behind the drumset, I had my ears wide open, and I was fully focused on the music.

I had the whole piece memorized with one listen.

Before I fell asleep last night, and my brain was processing five thoughts per second, the issue of memorization crossed my mind, and I began thinking about the musical prodigies of history.

Especially Wolfgang Amadeus Mozart.

Mozart was a musical genius; he demonstrated superhuman memory skills, he was incredibly talented, and intelligent. He had exceptional composition skills, and was proficient in almost every musical instrument of the time. I don't have the time to give you a synopsis of Mozart's life, but I recommend you watch the movie Amadeus, as it is quite accurate in the account of the events of Mozart's life, as well as his persona.

Mozart was known to have a photographic memory, which was well-documented in the movie. He could memorize an entire concerto with one listen. He would often compose entire symphonies in his head before committing one note to paper. His manuscripts were flawless. All these feats are even more astounding given the limits of 18th century technology. Last evening, while I was contemplating my rapid memorization of the Time Warp, I considered Mozart's uncanny mental prowess.

The memorization of large volumes of data has a lot to do with the way our brains manage and process information. Mozart must have used a number of tricks to allow him to store huge volumes of data, with little to no loss of data integrity. When I considered the way I memorized the Time Warp, I surmised that I used a type of mental data compression in order to assimilate a large amount of information in such a short period of time.

If I explain all this in musical terms, I will probably lose most of you with a bunch of jargon you may or may not know, so I have considered using a different analogy to convey my point.

First of all consider a landmark, or piece of architecture that strikes you with awe, at its' immense size or detail. Consider the Sistine Chapel. I have never been there, but even through photographs, I have been awestruck at the architecture and detail of the chapel. As a tourist, there is no possible way that one can absorb every detail, every crevice of the landmark, nor is it possible to absorb every detail Michelangelo painted on the ceiling. The level of detail is overwhelming. Strangely enough, we all have some recollection of the detail of the building.

Consider the process in which we all read. If you think way back to your youth, when you just began to learn how to read, you might recall it being a rather exhausting effort. I recall being taught to pronounce every single letter phonetically, and these letters became syllables, and then entire words. Entire words became phrases, and sentences; sentences became ideas; sentences became paragraphs, and paragraphs were representative of more complex ideas. You can extend this scale as large as you wish, but at the very root are individual characters.

When we memorize a sentence, a phrase, or poem, or any other written material, do you think we memorize every individual letter? If we tried to memorize every individual letter, we probably could not remember more than a few words. Our brains have become adept at recognizing words as individual units, instead of long strings of letters and punctuation. I am sure linguists and psychologists would argue that we memorize phrases, groups of words, even general ideas, as larger, more general pieces of information are easier for our brain to manage.

It's a lot like telling a joke you recently heard. You often remember the punch line, and you make up the rest. It's a way that we can assimilate large pieces of information. The important pieces are retained, and the rest is filler.

This is the same process that speed readers use to quickly assimilate large volumes of information, however it does take some training. When the common person reads, they do not read individual letters, much like a young child does, but their brain sees each word as individual units of information. Speed readers are able to go beyond the individual word and see entire phrases as one unit. They have learned to compress information at a higher level.

Contrary to popular belief, speed readers do not have photographic memories. When they are reading a page every ten seconds, they are only assimilating general ideas of the text. You cannot get them to quote passages word-for-word; instead they are looking at the bigger picture.

When I was listening to the "Time Warp" at last night's rehearsal, I was using the same tactic. Memorizing individual notes takes dozens of listens -- and takes far more time than I have available. I am sure Mozart similarly used these tactics to memorize entire compositions with only one listen.

What the layperson often does not know, is that music is a lot like spoken language; it has rules, grammar, and punctuation. There are rules to follow when writing music, there are motifs, and formulae which are used to develop musical themes. Composers of the Baroque, Classical and Romantic periods of music followed a much stricter code of composition then what is followed today. So, if a person was well-educated in the process of music composition, they could predict the direction a piece of music would take.

That being said, I am not criticizing Mozart by any means. He was far more talented than what I could ever hope to be. I consider him one of the most brilliant composers of all time. But the process I have outlined above is my hypothesis on how he could possibly memorize such huge volumes of music, and compose entire symphonies before placing one note on parchment.

On a slightly different tangent, the ability for the brain to process large volumes of information at the many levels I have described is likely the key to academic success at the post-secondary level. It seems that university students receive the greatest rewards when they can understand the bigger picture (macro), yet have the ability to memorize the important details at the "micro" level. Abstract thought, reasoning, deduction, and induction also play a large role in a student's level of success in their academic studies; which arguably, is related to a student's intelligence. Ultimately, a student will succeed if they can assimilate, process, and manage the information presented to them in a reasonable amount of time.

It was nearly too late in my academic career before I learned how to adequately manage the high volume of information I was given. I have my lousy grade-point-average to show for that. If I had learned those tricks two (or more) years prior to graduation, I would likely have a Ph.D. by now.

I am still considering the idea of returning to University to complete another degree. When I do, I am going to be unstoppable. I smell a 4.0 GPA in my future.

A Psychology Lesson Interspersed With Music

I cannot recall if I have ever discussed left-brained versus right-brained drumming on this weblog before. It is a rather complicated topic, with its' roots buried in Psychology rather than music.

Understanding the complexities of the brain is a huge academic undertaking, and even leading professors of Psychology will tell you that we still understand only very little of the workings of the brain. So, please accept this as my disclaimer that I know very little about the brain itself, but I know enough that I can make a few generalizations to further facilitate this entry.

The frontal lobe of the brain is divided into two halves: the left side, and the right. Both sides operate differently, and both sides are responsible for different aspects of thought, and reasoning. The left side of the brain is the logical side. It is highly mathematical, and rational, among other things, controls the actions on the right side of your body. The right side, is the more creative side of the brain, and controls actions on the left side of your body.

There have been many studies that have shown that artists are generally left-handed. This would make some sense since as just explained, the right side of the brain controls creativity. I am not going to develop this argument further, as I really don't have much knowledge of these statistics, but I would like to take this a step further as it pertains to music and drumming.

When a student takes lessons from an instructor (such as myself), they are provided with a number of exercises that helps develop the student's coordination and reading abilities. Exercises are little more than that - read, and execute in ad infinitum until proficiency develops. Exercises such as the above are logical, and thus only develop the left side of the brain.

Many of my students have developed a proficiency in exercises not unlike those described above, but when I ask them to just "play the drums", they fail miserably. What they play is tortured, rigid, and unmusical. The answer to why they cannot "play the drums" is simply because playing the drums without written material requires development of the right side of the brain.

Developing the creative side of the brain is much more difficult than assigning exercises that develop coordination. I am attempting to address this issue with some of my more advanced students to see how they take to this new approach. It will take a number of weeks, but I am going to see if they can eventually make music without the aid of written material.

Creative drumming is a lot like singing a song, or even speaking a sentence. Music is a language, thus it has conventions that are similar to written and spoken language. There are nouns, verbs, adjectives, grammar, and punctuation of sorts in music. Trying to get my students to speak in such a language is going to be a difficult task. The only way I think I can facilitate this is by starting very simply. Get the student to play some simple figures on the snare drum, and try to get them to develop on that idea. The ideas should be further developed by adding more complex rhythms, and colors such as toms and cymbals.

Applying the rudiments to this exercise is key to the success of this program. So far, I am going to spend a few weeks on the single-stroke roll, as this is the most often used rudiment, and likely, the most diverse.

I will also have to find a way that I can teach them how to listen to other players in order for the experiment to be a success. I have yet to determine the best approach to this idea. If my memory remains intact, I will update this weblog to indicate the degree of success of this experiment.
