In most jazz standards, the A-section is used to establish the key, while the B-section has tonal excursions, but in "Introspection", the roles of the sections are reversed. The A-section doesn't land on a stable chord until bar 6 where it lands on DΔ7, but the B-section establishes DΔ7 as a new key center. The last extended A-section finally lands on DΔ7 in the 4-bar coda. J Jackie-ing A through-composed 16-bar tune in the B lydian mode, that Monk named after his niece, Jackie Smith.
