Primarily a soloist, on rare occasions Gould did perform with singers, violinists, or chamber groups. His partners always found him easy to work with, cooperative rather than domineering.

Gould's familiarity with music, and piano music in particular, was extensive. However, his concert repertoire, and to a lesser degree his recorded repertoire, were focused on a limited number of composers, in particular Bach, Beethoven and Schoenberg. Other favourite or favoured composers were Gibbons, Handel, Haydn, Mendelssohn, Brahms, Richard Strauss, Sibelius, Berg, Webern and Hindemith. His attitude towards Mozart was ambivalent but he recorded all his piano sonatas.

Manuscript note from Israeli housewife, December 1958, reading: "Dear Mr. Gould! I am just an ordinary Israeli housewife. I know, you don't care about the public, almost hating us. Nevertheless, I will say thank you from all my heart, for letting us hear you playing. I went home changed for days to come. God bless you!"
Your cooperation will be appreciated…" – a polite explanation, undated, by Glenn Gould as to why he did not shake hands
