Choir directors will be delighted with Voiceworks, a superb resource for leaders of choral groups aged 11 to 14 ... This handbook covers all the areas a leader needs to know about. A detailed introduction is followed by sections on how to warm up the voice and rehearse. The section on boys' changing voices is particularly useful. The undoubted triumph of the publication is the very approachable material: 60 songs, from unison to four-part harmony.
