Abstract

The object of this article is to discuss, defend, and supplement the only definite piece of evidence we possess which deals with the musical scalesreferred to by Plato in the Republic . In this first section I shall consider the list of scales given by Aristides Quintilianus and suggest the source from which it is derived; in the second part the employment of certain abnormal intervals will be established and elucidated; and finally the evidence of the preceding sections will be reviewed from the standpoint of the Pythagorean musical theory
