This 24-bar dominant blues form is quite spacious, essentially being a stretched 12-bar, with each bar doubled. This produces a long opening stretch on the I7 chord through bar 8 that gives singers and soloists plenty of room to settle into the groove and develop ideas without needing to chase frequent harmonic movement. The first notable shift comes in bar 9, where the progression moves to IV7 rather than the more common V or ii-based change, giving the middle section a slightly unusual turn while still feeling accessible. After four bars on IV7, it returns to I7 for bars 13–16, before the final section becomes more active: two bars of V7, two bars of IV7, then another two bars of V7, followed by IV7 and V7 to close. Overall, it has a clear, traditional dominant-blues character, with a simple harmonic layout early on and more movement later for players who want to outline the changes more closely.
