How the tune works

C minorusual key
12 barsA form
C mkey centers

The tune is a 12-bar minor blues, three lines of four bars. Cm7 holds the first four bars. The second line moves to Fm7 for two bars and returns to Cm7 for two. In the third line, A♭7 in bar 9 and G7 in bar 10 lead back to Cm7 for the last two bars. A♭7 is the one chord that a plain minor blues does not use. Coltrane's record opens with a 14-bar introduction before the first chorus. C minor is the usual key. Coltrane recorded the tune a half step higher, in C♯ minor.

The changes in C minor, the usual key: 12 bars, three lines of four. The first line holds Cm7, the second moves to Fm7 for two bars, and the third turns through A♭7 and G7 back to Cm7.

Moved down a half step from the changes Roel's World and Wikipedia give for the recording in C♯ minor (C♯m7 for four bars, F♯m7 for two, C♯m7 for two, then A7, G♯7 and C♯m7 for two). Roel's World writes bar 9 of the Real Book version in C minor as A♭9; the recorded changes give A♭7 when moved to C minor. Coltrane's record has a 14-bar introduction that this chart leaves out. Compare the chart with the one you play from and with the recording.
