Here are a few images that I worked up for the sheet music tutorial. First of all here is the beginning of one piece of piano sheet music:

These are the values of each different note you see. It’s technically allowed to make notes as short as you need them to be, just add another line to the sixteenth note to divide it in half (just don’t expect to be able to play a 128th note).

Finally, here is the piano pitch chart. You’ll need to memorize this and be able to recognize any note in your sleep.
