Tools
Accidental calculator
Pick a key and a note letter and it tells you the sharp, flat, or natural that letter carries in that key, spells the note, and shows it on the staff.
Key signature finder
Pick a mode and a key and see its sharps or flats drawn on the staff, the scale spelled out, and its relative key named — then hear it played.
Key signature trainer
A key signature appears on the staff, you pick the major key it belongs to, and you get instant feedback and a running score.
Metronome
Set the tempo and time signature and practice in steady time, or open the Pro tab for subdivisions, per-beat accents, a speed trainer, a gap trainer, click sounds, and recording yourself under the click — all free, right in your browser.
Note finder
Pick a note and see every place it sits on the piano keyboard, named — and tap any key to hear it.
Note reading trainer
Practice reading the treble staff: a note appears, you click it on the piano. Instant feedback, the note plays, your score tracks.
Tap tempo (BPM tapper)
Tap the button or the space bar in time with any music and it reads the tempo back in BPM, with a matching tempo marking.
