Organized Chaos

It's not immediately obvious, but the LH is an inversion of the RH.
The individual notes do not matter as much as the sweeping gesture.

The recurring theme of organized chaos is one that I find to be especially compelling. In the early part of the 20th century, composers began to emphasize gestures in their writing rather than the individual notes themselves.  As a result, the ear is robbed of a tonal basis, and the music presents itself in a new and foreign language.  Though the pitches seem arbitrary, the level of detail that goes into the music is incredible, even when the gestures are not immediately obvious (e.g. Webern).  So while the end result can sound chaotic, one still feels an underlying logic that separates it from random pitches randomly placed in time.

What makes the notion of organized chaos compelling is how well it marries two seemingly contradictory ideas, and how pervasive it is.  It's not difficult to find parallels in life; in the case of the performer, it is a miracle that they can achieve any consistency at all in physically playing their instrument.  The brain sends and receives electric signals to move specific muscles in a certain way, but the brain must filter out a lot of "noise" to process these signals (much like tuning a radio).  Consistency, then, depends on sending a the same signal and consistently filtering it out the same way every time; the margin of error is tremendous!  Amazingly, the consciousness is able to bypass all of this: "Hear the sound in your head and it will come out through your instrument."

On a slightly larger scale, reality itself may very well be made of organized chaos.  Of all the possible realities for any point in time, the fact that (our perceived) reality chose the particular one that it did makes it virtually impossible to replicate.  It's complex and difficult enough to recreate the exact conditions of any given moment since that moment is the result of the infinite scenarios leading up to it, which brings back the familiar tenet, "Everything is related to each other [...]"

But even amidst the complexity and chaos, humanity is still capable of finding warmth and beauty. The universe works in funny ways.
