Grand Staff Lane
Notes travel from the right and should be played when the notehead reaches the vertical line.
Piano Input
The on-screen piano and the computer keyboard both count as live input for the timing lane.
Note Runner
Pick a singing range, choose a musical key, decide whether chromatic notes are fair game, then hit each note on the piano exactly when it crosses the line. Score builds on correct timing, misses reset your combo, and the timing halo tightens or widens with the slider.
