Why do singers sing in the way they do? Why, for example, is western classical singing so different from pop singing? How is it that Freddie Mercury and Montserrat Caballé could sing together? These are the kinds of questions which John Potter, a singer with the Hilliard Ensemble and Red Byrd, and himself the master of many styles, poses in this fascinating book, which is effectively a history of singing style. He finds the reasons to be primarily ideological rather than specifically musical. His book identifies particular historical 'moments of change' in singing technique and style, and relates these to a three-stage theory of style based on the relationship of singing to text. There is a substantial section on meaning in singing, and a discussion of how the transmission of meaning is enabled or inhibited by different varieties of style or technique.
