Drawn from his long experience as a cathedral lay clerk and solo singer, Peter Giles provides a comprehensive guide, from the making of the first sounds to acquiring the complete technique. The vital aspects of resonance, different registers, breathing and vocal agility are all carefully explained, in words and also with special drawings created by the author. There are graded vocal exercises to encourage the production of the sounds that have been so thoroughly explained - it is in fact the complete manual for the teacher and the would-be countertenor.
