Blue Monk was composed by Thelonious Monk and first recorded on September 22, 1954, for the Prestige label with a trio consisting of Monk on piano, Percy Heath on bass, and Art Blakey on drums. The tune became one of Monk's two most frequently recorded compositions alongside Round Midnight, yet it occupies a distinct place in his catalog as a blues piece rather than one of his more harmonically angular originals like Criss Cross or Brilliant Corners. The melody is built on repeating groups of even eighth notes punctuated by rests, creating a playful, loping quality that is instantly recognizable. Monk's performance technique on the piece often involved crushed or bent blue notes, such as briefly sounding a C-sharp against the major third D over the opening chord, producing a characteristic bluesy dissonance. Abbey Lincoln later added vocals to the tune under the title Monkery's the Blues for her 1961 album Straight Ahead, reportedly with Monk's personal approval after he visited the studio during the session. A notable live performance captured at the 1958 Newport Jazz Festival appeared in the concert film Jazz on a Summer's Day, bringing the composition to a wider audience. In an unlikely crossover, the jam band Phish adopted Blue Monk into their repertoire in 1987, initially cataloging it simply as an untitled swing tune before identifying the Monk original. The piece remains a staple of jazz pedagogy and jam sessions worldwide, valued for its melodic accessibility and its depth as a vehicle for blues improvisation.
