ARISTOXENUS

A Greek philosopher and musician, a native of Tarentum, and a pupil of Aristotle, lived about 330 B.C., and was a prolific writer on various subjects, but most particularly on Music. In contrast with the Pythagoreans, who referred everything to the relations of numbers, he regarded music as founded on the difference of tones as perceived by the ear. Of his Elements of Harmony, three books are preserved, but they are neither complete, nor in their original shape. Only a part of his Elements of Rhythm has survived.
