chordfold · harmonize your recording in the chord of the moment

Pull your hands apart and the take fans open into a chord of itself — diatonic to whatever chord the piece is playing right now, re-voicing live as the harmony moves.

Starting the current… Karel's piano plays untouched at rate 1.0; your hands add pitch-shifted copies that snap to the chord sounding at this instant, read from the take's own chord track. The light's hue tracks the harmony.
