This important source includes seventeen compositions (one of them in two versions) in a wide range of styles, from simple descant-style plainchant harmonisations to elaborate isorhythmic structures. Now reprinted with revised musical editions and expanded introduction and commentary, at the original price. For three or four soloists or small vocal ensemble. xvi + 61 pages.
