Gould had a pronounced aversion to what he termed "hedonistic" approaches to piano repertoire, performance, and music generally. For Gould, "hedonism" in this sense denoted a superficial theatricality, something to which he felt Mozart, for example, became increasingly susceptible later in his career. He associated this drift towards hedonism with the emergence of a cult of showmanship and gratuitous virtuosity on the concert platform in the 19th century and later. The institution of the public concert, he felt, degenerated into the "blood sport" with which he struggled, and which he ultimately rejected.
