Hand tracking runs locally in your browser (MediaPipe). Show one hand clearly; switching gestures switches the chord instantly. No camera? Use keys 1–8.
Melody Hand · lead instrument
Bar strip: raise/lower your hand to pick the note; it sounds only while your index finger is up. Circle wheel: your index fingertip is the pointer. Touch a slice to play its note, slide along the band for legato steps. The hollow centre is a sustain pedal — pull the fingertip in and the note holds while you reposition (its name shows in the middle). Move the fingertip outside the wheel to release the note. Jumps over notes go through the centre, so nothing sounds in between. Switch Pitch mode to Continuous for every microtone with a live tuner. The melody hand is drawn in blue and never triggers chords.

Tips: the metronome is never recorded. Pattern & tempo changes apply at the next bar, and chord changes land on the ½-bar/bar (set "Chord change" in Options) so the groove never stumbles — the blue →chord in the top bar shows what's coming. Press A during a quiet verse to melt into fingerpicking, and again for the chorus strum — same tempo, seamless. Use the capo to match your singing key.
