Dexterity is a bebop composition by Charlie Parker, first recorded on October 28, 1947 for Dial Records with his quintet featuring Miles Davis on trumpet, Duke Jordan on piano, Tommy Potter on bass, and Max Roach on drums. The tune is a contrafact based on the chord changes of George Gershwin's I Got Rhythm, one of the most widely used harmonic frameworks in jazz. Parker wrote numerous melodies over these changes, and Dexterity stands among the most technically demanding of them, its title reflecting the virtuosic facility required to navigate its rapid, intricately winding bebop lines at speed. The melody is quintessential Parker, full of chromatic passing tones, unexpected rhythmic accents, and fluid intervallic leaps that define the bebop vocabulary he pioneered. Like many rhythm changes contrafacts from the bebop era, the composition transforms familiar harmony into something fresh through the sheer inventiveness of its melodic content, making the underlying chord progression feel new despite its ubiquity in the jazz repertoire. Dexterity became a staple of the bebop and hard bop jam session tradition, recorded by numerous musicians across generations. Notable among its interpreters is Paul Chambers, who included the tune on his 1956 album Chambers' Music with John Coltrane on tenor saxophone and Kenny Drew on piano, bringing the piece into a hard bop context that demonstrated its enduring vitality nearly a decade after Parker first committed it to record.
