HS2 · Duet Hands EXPERIMENTAL

HS2 — a two-handed duet
🫱 Right hand = melody. Raise / lower your hand to change pitch (snapped to the key). Pinch thumb + index together for louder. Rotate the hand for a brighter or darker tone.
🫲 Left hand = chords. Raise / lower to move through the chords of the key. Open your hand to swell the chord; make a fist to mute it.
🎶 Both hands share one key & scale, so the melody always fits the chords.
📸 Best strapped to your chest with the rear camera facing your hands. Use Swap hands if the roles feel reversed.
