Final answer:
Stuart Davis was influenced by jazz music, and his work 'Mellow Pad' reflects the slang and energy of this American musical style.
Step-by-step explanation:
Stuart Davis, an influential American modernist painter, was deeply affected by the world of music, particularly by jazz, a genre that epitomized 1920s culture and the Harlem Renaissance. Drawing inspiration from this uniquely American music style, Davis's work 'Mellow Pad' from the 1940s incorporates slang of the time, reflecting the energy and rhythm of jazz. Many jazz musicians, including Duke Ellington and Cab Calloway, became icons in Harlem nightclubs such as the Cotton Club, and their influence permeated the arts, touching visionaries like Davis who sought to capture the essence of jazz in visual form.
