Question: what are the notes in happy birthday on piano?
Answer: To prepare, ask the child to play and name the notes C, D, E, F, G with the right hand 1, 2, 3, 4, 5 both up, and back down again. Then do the same with the left hand going downwards (they will find this more difficult at first) C, B, A, G, F and back up again to middle C.
