sandpile music

Here are some pieces of music created using the abelian sandpile model. See my paper (BRIDGES conference, 2019) and the accompanying talk for an explanation of the dynamical system and how it generates the music.

A IV-V-I progression on a 15x15 grid

A piece on a 9x9 grid where the x-axis modulates note length and the y-axis modulates note onset

A longer piece on a 41x41 grid.

Three small examples on an 11x11 grid: I II III

A few experiments with random note values: I II III
