Gr 4-9- With energetic conductor Marin Alsop as a guide, Helsby has created a guide to instruments commonly found in an orchestra. Alsop's introductory essay establishes the friendly, accessible tone of the book: "Being a conductor is very much like being the captain of a team...." Utilizing large print; ample, colorful illustrations; and an open format, the book is logically organized into chapters about each of the musical instrument families, including keyboards, the voice, and modern electronic instruments. Throughout, readers are prompted to listen to the accompanying CD-ROM, which features more than 100 musical samples. Information is clearly presented, and the author's enthusiasm for her subject is contagious. Readers will enjoy browsing through the volume, and music teachers will welcome it with enthusiasm. While there are many other books on this topic, this one is the most comprehensive and accessible.-Lee Bock, Glenbrook Elementary School, Pulaski, WI Copyright 2008 Reed Business Information.
