His Blue Note LP One Flight Up includes a fine reading of the Jimmy Van Heusen ballad “Darn That Dream” on which he dexterously employs a device favored by Charlie Parker. This maneuver involves momentarily raising the key a half-step and inferring a ii-V progression in that key.
Here are two instances in which Dexter deftly employs that ploy. As anyone who has ever tried to transcribe his solos knows, one of the hallmarks of Dexter’s style is his unique approach to rhythm. While his languid phrasing is pure joy to hear, it’s a nightmare to transcribe. I have greatly simplified the rhythm in these two examples, focusing instead on the pitches Dexter chose for the brief modulation.
