This dense but lively treatment of Telemann's instrumental music fills a real void. While many musicians of his era have entire shelves devoted to their work, the Telemann section in my college library contains exactly three books about Telemann's life and music, most of which are superficial. But this book does not skim across his oeuvre; instead, it spends 500 pages analyzing the forms and precursors of his prolific output, with many examples and excerpts. Yet a warning must be issued up front--this is not for the casual reader or even a serious amateur. The prose is thick with technical musical form analysis and terminology, including numerous French, German, and Italian terms that remain untranslated, and might even challenge a music major. And in a book with almost 200 pages of notes and bibliography at the end, the most needed end section of all for the interested layman, a Glossary, is almost laughably inadequate. There are often more obscure terms on ONE page of the text than can be found in the entire glossary. And yet, in spite of these caveats, there are clearly interesting and tantalizing insights lurking just behind this veil of technical jargon, and a sense of a very good writer in complete control of his subject. As an amateur musician who loves and often plays Telemann, I intend to struggle through the entire book or die trying. While it is hard for any writer to please all audiences, I just wish the author had kept the many intelligent amateurs like myself in mind when he wrote this, instead of a small circle of academic experts.
