Book excerpt: The complex art of conducting may look effortless to the casual onlooker, however, it requires a great deal of knowledge and skill. The success of a performance hinges on the director's ability to keep the group playing together and interpreting the music as the composer intended. The Complete Idiot's Guide® to Conducting Music shows student and novice conductors how to lead bands, orchestras, choirs, and other ensembles effectively through sight-reading, rehearsals, and performances.
