Book excerpt: Structure and Style, first published in 1962 and expanded in 1979, fills the need for new ways of analysis that put 20th-century music in perspective. It spans forms in use before 1600 through forms and techniques in use today. Anthology of Musical Forms provides musical examples of forms treated in Structure and Style. Some examples are analyzed throughout. Most are left for the student to analyze. These books reflect Leon Stein's impressive background as student, musician, and composer. Stein studied composition with Leo Sowerby, Frederick Stock (conductor of the Chicago Symphony) and orchestration with Eric DeLamarter, his assistant. He earned M. Mus and Ph.D degrees at DePaul University and was associated with its School of Music as director of the Graduate Division and chairman of the Department of Theory and Composition until his retirement in 1976. He has composed a wide variety of works, including compositions for orchestra, chamber combinations, two operas, and a violin concerto.
