In this reprint from 1959, Parrish describes the development of music notation from the ninth century to the beginning of the fifteenth century. He discusses medieval notation using 62 facsimiles from the Ars Antiqua through Ars Nova eras as examples and outlines common principles of each period, with discussion of specific instances in the facsimiles. The book is intended for use in undergraduate and graduate courses on notation. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
