Down in fifths (C → F → B♭ …) is the classic routine — all 12 keys bring you back to the start.

Chords & length

Backing

Turn off comping to play the chords yourself; bass and drums alone feel closest to a real jam.

Display

Full chord: the root sits at the bottom, so the notes always match the chord symbol — best for beginners.
Jazz voicing: the root is left out (the bass covers it), so Dm7 reads F–A–C–E with no D — this is what a jazz pianist’s left hand actually plays, and the voice leading is smoother. Gold marks the 3rd and 7th — the guide tones.

Focus mode hides every setting except tempo and play. Tap anywhere to bring back the exit button.
