Ragtime music needs to be included!!
Especially from Scott Joplin (18681917) (Maple Leaf Rag), the King of Ragtime (Brun "The Ragtime Kid" Campbell was his only white student). And from Arthur Marshall (Swipesy Cakewalk, w/ Joplin)(I heard him play it in 1960), James Scott (Hilarity Rag), Charles Johnson (Dill Pickles Rag), Scott Hayden (Something Doing), Louis Chauvin (Heliotrope Bouquet), Blind Boone (Southern Rag Medley No. 2), and many, many more.
Definitely!
