A collection of more than 230 program notes of chamber music composed by 55 composers. The author is himself an enthusiastic chamber music musician and program annotator. Typically, he offers a biography of each composer followed by descriptive notes about each composition. The text is generally readable, though not penetrating; the book will appeal primarily to the casual listener rather than to the student or musician. Berger has managed to find subtitles nobody knew existed: one wonders if any real service is performed by listing ``Werther'' as a subtitle for the Brahms Piano Quartet Op. 60. Recommended, with reservations, for public libraries with record collections. William Shank, CUNY Graduate Sch. Lib.
