How Deep Is the Ocean?, recorded November 4, 1947, is a ballad performance by the Charlie Parker Sextet on the Irving Berlin standard in E-flat at approximately 70 BPM with a 32-bar ABAC form. Uniquely among the tracks from this session, the only cataloged solo is J. J. Johnson's half-chorus on trombone, making this a relatively rare showcase for the trombonist within a Parker session. Johnson's ballad playing reveals a warmth and lyricism that complements his more celebrated up-tempo work, demonstrating the full range of his musicianship. The ballad tempo and the rich harmonic landscape of Berlin's composition provide an intimate setting that contrasts markedly with the high-energy performances that dominate the rest of this recording date. How Deep Is the Ocean? captures a quieter, more reflective moment from the November 1947 Dial sessions and offers a window into the musical personality of J. J. Johnson, who was establishing himself as the most important trombonist in modern jazz during this period.
