Piano

Guitar

Play on either instrument and the other follows. Tap a key or fret to toggle it, tap a string name to switch it open or muted.

Shapes are generated for the selected name. Guitar shapes stay within a four-fret reach and keep the chord's bass note on the lowest string; for chords of four or more notes the 5th may be left out. Press Load on any card to send it to the input above.
