“Bags’ Groove” is a blues composed by vibraphonist Milt “Bags” Jackson and recorded in 1952. Miles Davis’s 1954 recording with Jackson, Thelonious Monk, Percy Heath and Kenny Clarke is a jazz landmark, partly because of Monk’s sparse, unusual comping.
The form is a 12-bar blues in F. The melody is a simple, catchy riff, and the harmony follows a standard jazz blues with a ii-V and turnaround.
Section by section: in bars one to four, use the F blues scale and short riffs. In bars five and six, move to Bb7 and target D or Ab. In bars nine and ten, outline the ii-V with guide tones, and in bars eleven and twelve, use a turnaround lick. Monk’s comping on the Miles recording shows how space can create tension and interest.
Practice with a blues play-along. Learn the riff by ear.
Transposing tip: Bb instruments read it in G, Eb instruments in D.
Arrangement idea: feature vibraphone if you have one, in tribute to Milt Jackson. Trade fours with the drummer before the last head.
