Music notation
From Just Solve the File Format Problem
Music is said to be the universal language. Various notations have been developed to express the sounds of music in a manner independent of the spoken or written language which expresses words; while not actually "universal" because they can be tied to particular cultures just as languages are, many of these notations have wide global use. On paper, musical notation is generally called "sheet music", and it is used by musicians to guide them in playing a musical piece on their instruments. Many systems have been devised to store and express musical notation electronically.
