Music Theory Modes and Chord Scales

The simple tool below shows the chords available in any given mode.

The Seven Modes

Ionian mode is the major scale. Aeolian mode is the minor scale.

Example: if you're writing a song in a major key, you can use any of the chords in the Ionian mode, and it will sound good.

Checking the "Use 7th chords" box will add color to the sound and probably make it sound a little more jazzy.

The Tool

Enter the root note of your key in the input box, and optionally check the "Use 7th chords" box. Click the chord boxes to hear the chords.
