Triadic Memories is one of Morton Feldman's most popular and frequently performed works for piano. Here, more than is usual in his music, Feldman uses the repetition of patterns and gestures. The repetitions are rarely exact – they are characterized by very subtle rhythmic variations – but almost every gesture, whether large or small, is repeated a few or many times. The repeated figures, while all being quiet and relatively simple and brief, vary in their length, structure, and texture. The unpredictability of the number of repetitions, the asymmetry of the repeated figures, the avoidance of a regular pulse, and the subtlety with which Feldman alters the repetitions keep the music continually intriguing for the attentive listener.
