Harmonic Wheel

Based on a single note, the Harmonic Wheel calculates the root of triads, 4 notes chords, major modes, and melodic minor modes that contain the selected note. Example: C, F, and Ab major triads all contain the note C. This tool was designed to help composers explore harmonic sounds that may not be obvious.
