The Solitude Trilogy is a collection of three hour-long radio documentaries produced by Canadian pianist Glenn Gould (1932–1982) .
Gould produced the documentaries as individual works between 1967 and 1977, then collected them under the title Solitude Trilogy, reflecting the theme of “withdrawal from the world” that unites the pieces.
The three pieces employ Gould’s idiosyncratic technique of simultaneously playing the voices of two or more people, each of whom speaks a monologue to an unheard interviewer. Gould called this method “contrapuntal” radio. (The term contrapuntal normally applies to music in which independent melody lines play simultaneously; this type of music, exemplified by J. S. Bach, was the major part of Gould’s repertoire.)
