Množina: notations

A system representing music graphically as successive values in pitch and time. By 1700 modern notation had displaced plainsong and tablature notations, making possible the coordination under one system of orchestras of increasing size, and also making possible the composition of large-scale musical forms. Notation embodies the assumption that pitch and time are uniform and continuous, hence it relates to the development of keyboard instruments, the tempered scale, and chronometric time-keeping.
The earliest system was developed by the ancient Sumerians; later the Greeks and Romans devised systems for their music dramas. The system in use today goes back to the Middle Ages, to the Italian monk Guido d'Arezzo 1026.
