Frequent questions
How are chord shapes chosen?
An algorithm searches every playable shape within a 4-fret span and ranks them by ease: open strings, fewer fingers, root in the bass.
Can I hear the chord?
Yes, tap any diagram. Strings are synthesized with a physical string model; piano chords with additive tones.
