Composed and published in 1918 by Bob Carleton, a club pianist in Illinois and U.S. Navy Reserve member, "Ja-Da" (full title: "Ja-Da (Ja Da, Ja Da, Jing, Jing, Jing!)") became one of the most enduring novelty songs of the ragtime era. Published by Leo Feist Inc. with proceeds benefiting the Navy Relief Society during World War I, the tune was first recorded by Arthur Fields in 1919 and popularized by Carleton himself performing with singer Cliff Edwards. Its simple, catchy 16-bar structure features a playful ragtime-inflected melody built around a nonsense scat-like refrain, with straightforward harmony enriched by chromatic turns that proved surprisingly conducive to jazz improvisation. The tune's chord progression would later serve as the foundation for Sonny Rollins' 1954 composition "Doxy," one of the most celebrated contrafacts in the bebop repertoire. Carleton's signature hit helped bridge the gap between ragtime and emerging jazz styles, attracting interpretations from jazz luminaries including the Original New Orleans Jazz Band (1918), Tommy Ladnier and Sidney Bechet (1938), Bunk Johnson and Don Ewell (1945), Louis Armstrong, Oscar Peterson, Erroll Garner, and Marian McPartland, ensuring its place in the American songbook.
