Sing a chord. Light up the room.

Press Start, then sing the notes of a chord one at a time, like do – mi – sol. Start on any note you like. Pause for a moment when you finish and the chord it heard will light up.

Tips: sing each note for about half a second, with a little space between notes. Sing at least three notes. Add a fourth for the seventh chords. A quiet room and a mic close to your mouth work best.
