Glenn Herbert Gould was a Canadian pianist who became one of the best-known and most-celebrated classical pianists of the 20th century. He was renowned as an interpreter of the keyboard works of Johann Sebastian Bach. Gould's playing was distinguished by a remarkable technical proficiency and a capacity to articulate the contrapuntal texture of Bach's music.
Gould rejected most of the standard Romantic piano literature by Chopin, Liszt, and others, in favour of Bach and Beethoven mainly, along with some late-Romantic and modernist composers. Although his recordings were dominated by Bach and Beethoven, Gould's repertoire was diverse, including works by Mozart, Haydn, and Brahms; pre-Baroque composers such as Jan Pieterszoon Sweelinck and Orlando Gibbons; and 20th-century composers including Paul Hindemith, Arnold Schoenberg, and Richard Strauss. Gould was known for his eccentricities, from his unorthodox musical interpretations and mannerisms at the keyboard to aspects of his lifestyle and behaviour. He stopped giving concerts at the age of 31 to concentrate on studio recording and other projects.
Gould was also a writer, broadcaster, composer and conductor. He was a prolific contributor to musical journals, in which he discussed music theory and outlined his musical philosophy. He performed on television and radio, and produced three musique concrète radio documentaries called the Solitude Trilogy, about isolated areas of Canada.
