Some of the chapters of the book The history of music and composers, Choral and Vocal Music, Music for the Stage, Music for Solo Instruments and for Chamber-Music Groups, Orchestral Music, Music for Children, A Glossary of Basic Terms in Music.
I bought this book because I was impressed by the section on children's music (ie classical music written for a child audience in mind, not for children to perform) at the end. I look forward to reading it. Overall it looks like a good reference book to have around too.
