Rotating 10 regular polygons on the circle of fifths to produce musical sequences.

The first couple of regular polygons (the triangle and the square) have easy-to-foresee musical results, but others are not so obvious until you see/hear them!

This visualization was written in Java using a graphical library called Processing (https://processing.org), and Java's built-in MIDI library for sound (package javax.sound.midi).

0:00 Triangle
1:17 Square

5:04 Octagon
6:08 Nonagon
7:13 Decagon
