Each letter is a note; C D E F G A B are the octave starting at middle C, lowercase c d e… the octave above. Add , to go an octave down or ' to go up. The number after a note is its length: with L:1/4, A is a quarter, A2 a half, A3 a dotted half, A/ an eighth. z is a rest, ^ sharp, _ flat, = natural, | a bar line, and - ties to the next note. T: is the title, K:G the key, M:3/4 the time signature and Q:1/4=100 the starting tempo.

Play and stop with the space bar or a page-turner pedal (Page Down / Page Up); on a touch screen, tap the score. The page address always holds the current notes and settings, so Copy link shares exactly what you see.
