Dewey Square is a Charlie Parker bebop tune that was first recorded on October 28, 1947 for Dial Records at WOR Studios in New York City, with Miles Davis on trumpet, Duke Jordan on piano, Tommy Potter on bass, and Max Roach on drums. The changes are very similar to Gershwin's Oh, Lady Be Good!. It was released in 1948 as a 10-inch shellac single on Dial Records (catalog 1019), paired with This Is Always; the A-side features Parker's quintet. The track sits in the early post-war jazz era and showcases Parker's fast virtuosity and advanced harmonic language.
