Final answer:
A likely composer of pieces drawing from traditional Americana folk songs is Stephen Foster, America's original pop star, who artfully blended African and European musical traditions.
Step-by-step explanation:
Given the influence of traditional Americana folk songs, a likely composer who drew from such sources is Stephen Foster. Known as America's original pop star, Foster was adept at blending African and European musical traditions to create hits like "Camptown Races" and "Oh Susanna." His upbringing in Pittsburgh, where he was exposed to the music of African American boatmen and received classical training, helped him to develop a uniquely American sound that achieved widespread popularity and has continued to influence music into the 21st century. Despite his tragic end, dying penniless at age 37, Foster's legacy endures, and his methods set a precedent for future musical genres.
