Below is a graphical representation of a score I have in mind.
The score starts with soft, random notes moving in waves like particles affected by a gentle wind.
As the listener/viewer moves the mouse to different places on the spectrum, in this case the X axis and Y axis of the canvas, the color of the sound changes in gradation.
Each time a listener clicks on the canvas, the music gets louder, and the rhythm gets stronger, as if the particles are more and more affected by the force of gravity.
In the end, as the color fills up the canvas, the music morphs into a bold, constant sound.
