Repeats, DS, DC, Coda
Sections of music are often performed more than once. Repeat mark, ending, D.S., D.C. and CODA symbols are used, mostly in order to save paper (and sometimes page turning). Repeat marks appear in pairs (left and right) except when a section of music repeats back to the very beginning of a piece.
