Ionian Mode: Interactive Piano & Guitar Reference with Chords

Get the muted.io desktop app

🎨 A visual piano and guitar reference to the Ionian mode, which is the same as the major scale. The Ionian mode is the 1st mode of the major scale. The Ionian mode is simply the major scale, unaltered.

The reason why we have a mode like Ionian that is the same as the major scale, and hence two ways to name the same set of notes, is because modes came before scales.

This reference includes the notes and chords on the piano keyboard for each key of the Ionian mode.

Ionian mode formula:
1 - 2 - 3 - 4 - 5 - 6 - 7
