In an attempt to loosely codify the performance of both structured and aleatory musics, graphic scores provide a brave attempt at visualizing sound, silence, pitch, duration, etc. This often takes the shape of some kind of geometric abstraction, and can be viewed as a work of art unto itself. Most of these scores certainly leave room for interpretation by the performer. This, and another 20th century tradition, artistic appropriation, provided the impetus for the above video. See if you can see the sound's connection with the waxing, waning, and disintegrating geometry.
