Whack A Note is a Musical Note Reading Game inspired by the classic "whack a mole" game but with a twist. Select between 3 clefs (Treble, Bass, Alto) to test your note reading skills. Heres how this music gane works. The game starts with a random note being displayed (A-G in 2 octaves). A music card (note on staff) will begin to pop up from their holes at random.
