In music notation, dal segno al fine is abbreviated "D.S. al fine" and is written just above the staff. It indicates that the piece repeats a second time from the sign (dal segno), but stops at the fine rather than continuing all the way to the end of the piece.
When used on a staff, it looks like this (complete with time signature and a quarter note scale):
/\ $ fine
