Piano Chords: keys + accordion
About this app
Play melody and chords together on your phone.
This piano app is built for thumb-friendly playing: use your right thumb for the melody and your left thumb for chord buttons placed near the top-left of the screen. You can also switch to a chord-only keyboard in Settings.
The chord layout is inspired by the Stradella bass system used on accordions. It gives you five rows of buttons: bass, counterbass, major, minor, and dominant seventh chords. Notes are arranged around the circle of fifths, so related chords sit next to each other.
For C major, F major is on the left and G major is on the right. For A minor, D minor is on the left and E major is on the right.
Try the included demo melodies, then record your own music. You can share a recording as a link, or export it as MP3 or MIDI.
