Happy birthday to me. The trouble with piano notation is that it is numbered by notation, so you don't have to go to other websites to copy it.

444444443 1 14 14 44432 1 34 444546562 23444444545 4444453 1 14 1 3 4443265438. 1 6 65465 (low octave: 6 down 7) 14 4323 (low octave: 6 down 7) 16 6544 (low octave: 6 down 7) 16546546 down 765 4546 65465 (low octave: 6 down 7).

I wrote it myself, I hope I can understand it. .
