The purpose of this thesis is to give a perspective on the music theory of Ancient Greece & Rome through the study of original texts. Nine major theorists' treatises are discussed under the separate title, repectively. And also 7 minor theorists' treatises or theories are mentioned also in the course of discussion in relation to the major one. The rise of Western music theory can be traced back to the time of Pytagoras. His mathematical calculation of intervals set up the long tradition of treating music as mathematical scholarship. And the other branch of music theory was established soon also. That was an empirical one initiated by Aristoxenus who was a pupil of Aristotle. And then these two branches interacted in the course of development of music theory. That is, although most of the ancient theorists belonged to the Pytagorian school, those representatives such as Euclid·Ptolemy·A. Quintilian accommodated some of Aristoxenus' theory. Theorists represented the Aristoxenian school were Cleonides(cf. footnote 3) and Cassiodorus(cf. footnote 23). The topics dealt with in ancient treatises were intervals, scales, modes, scale systems, rhythm, tuning, notation, ethos of music, and Pytagorian concept of music of spheres. Intervals were discussed in depth particularly in relation to tuning (Ptolemy), tetrachord which was the basis of scales (Aristoxenus, A. Quintilian), and modes (Ptolemy, Gaudentius). The scale systems of the Greater Perfect system and the Lesser Perfect system became the norm throughout the ancient times. Of the rhythm, feets mentioned first by Aristoxenus were clearly explained and expanded by St. Augustine. Information on Greek notation relies on Alypius. Ethos of music and the idea of music of spheres were presented in length especially by Ptolemy and Boethius.
