How the tune works

C minorusual key
12 barsA form
C mkey centers

The tune is a twelve-bar minor blues in C minor, played in 4/4 at a fast swing. Bars 1 to 4 stay on Cm7. Bars 5 and 6 move to Fm7, and bars 7 and 8 return to Cm7. Bar 9 is A♭7 and bar 10 is G7, which pulls the chorus back to Cm7 for bars 11 and 12. Some charts add a B♭ over C in the second half of bars 3, 7 and 11. Coltrane's solo on the 1959 recording stays on plain Cm7 in those bars.
