Harmonize: an app for exploring scales and chords

This is an app that lets you select a note and scale, and shows you all of the diatonic chords for that scale.

It also allows you to highlight notes, which can be useful for exploring their distribution among those chords.

The app is at /~moondog8/apps/harmonize/ for now.
