A Study of Gregorian Rhythm, by Dom Andre Mocquereau, is the great classic by the master of the second generation of Solesmes chant scholars, the results of a lifetime of study of chant manuscripts and a spectacular effort at making the chant of the Catholic Church accessible to the world. He explains his perspective on rhythm, notes, typography, and provides a remarkably detailed explanation of each neume and why and how Solesmes did the work that it did. The English translation originally appeared in two separate volumes, only the first of which appeared in English in two parts. This is the two parts in a single volume of 440 pages, bound in softcover. The Mocquereau legend is larger than life: here you can read and learn from the master musician and scientist on his own terms.
