pi10k is a fun little flash gadget which allows you to choose up to ten notes. It will then play back those notes using the first 10,000 digits of pi.
Sit back, it’s a long little song you’re going to be hearing.
Some of my favorite progressions:
A minor Harmonic
(A B C D E F G# A B C)
This one comes out sounding like a Bach fugue or something. Makes you wonder…
D Major + 2nd
(D E F# A D E F# A D E)
