MyChordBFF showing guitar fingerings, chords in C major, next-chord suggestions, and a progression grid.

Chord suggestions

Chords in key,
and ways beyond it.

Suggestions follow music theory and established chord patterns. MyChordBFF does not use AI to generate music. You choose and arrange every chord. Here are three examples in C major.

Natural

CDmGC

Chords from C major move through preparation and tension, then return to C.

Tension

CA7DmG7

A7 introduces a note outside the key, creating a stronger pull toward Dm.

Borrowed

CFFmC

Fm borrows from C minor, adding a darker turn before the return to C.

Look ahead offers a pattern continuation and short harmonic routes with chords you can drag into your progression.

  • Follow a progression

    Look ahead offers short continuations based on harmonic relationships and common patterns. Listen to a route, then drag individual chords or the whole phrase into your progression.

  • Guitar sound and fingerings

    Preview acoustic guitar chords and see their fingerings. Auditioning leaves your writing position in place.

  • Arrange by touch

    Arrange up to 16 chords by touch. Reorder, undo, loop playback, save progressions, and share the chords as text.

Saved on your iPhone
