“Eighty-One” and Ron Carter (105) Standards Rating 5:  Difficulty Rating : 6

“Eighty-One” is a 24-bar tune with a 12-bar A section and a 12-bar bridge, written in F and first recorded on E.S.P. (1965). Though credited in The Real Book to Miles Davis/Ron Carter, the piece is widely regarded as Carter’s, and it reflects his expanding role in the Second Great Quintet. Carter’s concept—shaped by intervallic thinking, pedal points, and harmonic ambiguity—defines the tune’s character. The chart’s instruction to play even eighth notes places it firmly in a post-bop context, prioritizing articulation and interaction over swing’s triplet lilt.The melody is spare and rhythmically precise, using quarter-note triplets, unexpected pickups, and extended rests to make space a compositional element. Harmonically, the near-constant use of 9sus4 voicings—avoiding the third—creates an open, floating soundscape.. “Eighty-One” stands as a concise statement of Carter’s modern jazz language: economical, flexible, and deeply interactive.
