A proper understanding of these instruments depends on a clear grasp of their acoustical behaviour, as influenced by the properties of mouthpiece, pipe, and bell. A full discussion of these matters therefore forms the opening chapter; this is followed by an introduction to the instruments' basic characteristics and nomenclature. The instruments' historical development is explained in detail, followed by a description of valve systems, materials, and manufacturing techniques. Their capabilities and place in the orchestra--baroque, classical, modern, and jazz--are equally fully considered, and information is given about celebrated players. Apart from numerous photographs there are some sixty-six line drawings in the text.
