This generates four notes (twelve possible: a, b, c, d, e, f, g, a flat, b flat, d flat, e flat, and g flat) when you press space. I may add a "repeat/ don't repeat notes" option or a "play notes" option later in the updates. You can press space to refresh.
Inspired by this video: https://www.youtube.com/watch?v=hvECZ_ZXGqs So, I decided to try it myself! Enjoy. Change Log - June 4: First released
