African-based rhythmic patterns such as tresillo and its variants, the habanera rhythm and cinquillo, are heard in the ragtime compositions of Joplin and Turpin. Joplin's "Solace" (1909) is generally considered to be in the habanera genre: both of the pianist's hands play in a syncopated fashion, completely abandoning any sense of a march rhythm. Ned Sublette postulates that the tresillo/habanera rhythm "found its way into ragtime and the cakewalk," whilst Roberts suggests that "the habanera influence may have been part of what freed black music from ragtime's European bass."
