Crypto Notes is a collection of (almost) all musical notes that make up our music.

Collect the notes of your favourite song or put together a nice chord. The most common ones are quarter notes, but there are half, whole, eighth and sixteenth, too.

Starting with the octaves in the middle, this collection will once hold all notes you can find on an 88-key piano. Sharp and flat variants (aka the black keys) will count as separate notes, so the total number will be even higher at 124.
