About this game
Sharps and flats (accidentals) tell you to play a black key, or sometimes a white one, instead of the natural note. In this free game you match notes with accidentals to the right keys on the piano, against the clock.

Tips for beginners
A sharp (#) raises a note by a half step: play the very next key to the right. A flat (b) lowers it by a half step: play the very next key to the left. Most of the time that's a black key.
For teachers and parents
For students who already read the staff and know the black key names. It prepares them for key signatures and for accidentals in their pieces.
