This makes the fourth musical encyclopedia of the year, but there is already a place for this with those who own the Oxford series of ""Companions"". In alphabetical order, all aspects of musical history are covered, composers, their lives and works, notation, instruments, the dance, criticism, publishing, broadcasting, types of music. There are special articles on specific subjects. Richly illustrated. Tables of notation and nomenclature, pronouncing glossary, and reader's synopsis.
