This book is the first comprehensive study in English of Glenn Gould as a pianist and interpreter of music, and draws on a wide range of Gould performances and Gould literature. While focused on his performances, it situates his work and thought within broader musical, cultural, and historical contexts. The book is divided into two parts: the first exploring Gould’s aesthetic premises, the second characteristic features of his piano style. The book is illustrated with graphic musical examples and plates.
