Chord Assistant – Circle of Fifths

The Circle of Fifths mode of the Chord Assistant shows the chords in an interactive visualization of the circle of fifths.

The origin chord that defines the current key is shown in the center of the Chord Assistant and is marked as tonic (I).

The outer circle shows the twelve major chords ordered in intervals of fifths.

The inner circle displays the corresponding parallel minor chords.

The roman numerals mark the chords of the current key with their scale degree. You can use these chords to create typical chord progressions or you can use the other chords for more creative results.
