Song2Keys turns piano practice into falling notes

Field notes

Song2Keys offers three practice modes: Wait pauses until the player hits the required keys, Rhythm scores timing against 50 ms and 150 ms thresholds, and Listen lights the keys during playback. The catalogue ranges from beginner pieces such as Burgmüller’s “Innocence” to advanced works including “Clair de Lune,” with durations and note counts shown for each. The page also states that MIDI files stay in the browser and that PDF scores become private practice songs.
