‘Anyone interested in the evolution of post-World War II music, particularly in terms of musical structure and thought, will find profound insight in the detailed analysis of the music of German composer Karlheinz Stockhausen.Spanning three volumes, the analysis covers distinct phases of Stockhausen's work, from structural serialism, intuitive music, and moment-form, to his later development of formula-composition, culminating in the monumental work Licht, Stockhausen’s seven-day opera cycle. Flo Menezes, who personally knew several key composers of the second half of the 20th century, including Luciano Berio, Henry Pousseur, and Pierre Boulez, taught analysis classes at the Stockhausen Summer School in Kürten, Germany. Menezes even surprised Stockhausen by revealing structural insights in Studie 2 that the composer himself had not been aware of.Although Menezes’ writings primarily focus on Stockhausen's work, readers will find it to be a profound treatise on composition in the second half of the 20th century.’Hans Tutschku, Fanny P.
