An extremely useful book, designed to concentrate in brief compass a great deal of basic information about varying musical forms, historical development, and high spots of representative compositions in the various fields of orchestral music, opera, chamber music, and so on. No attempt to go into the biographical aspects of composers' lives, but very definitely presents them in relation to their contribution to music. Untechnical enough to be a good ""first steps"" for the amateur and the listener-in. The book is based on an English publication, from which careful abridgements have been made for the American market. More practical than Mme. Stokowski's new book, The Leyman's Music Book.
