The note cruncher is a tool that allows you to explore your own chords and scales.

By entering any pattern of notes and then either filtering or expanding the results, you can generate your own custom lists of chords and scales based on your own preferences.

For example, if you like jazz, you might want to enter your favorite jazz chords, then find out all the possible transpositions of those chords.

Or, if you are into world music, you might want to enter an unusual scale, then find all the modes of that scale.

The possibilities are endless.
