Random Chord Generator

This started out as a demo I created for a combinatorics class to generate necklaces. It occurred to me that musical chords were basically combinatorial necklaces, and I wanted to see if I could uniformly generate a chord and create an interactive tool that could play them.

Once I did that, I extended it further: you can enter the number of notes you want in the scale, and have it generate and play a chord. You can also just use your mouse to click on the individual keys, if you like.
