the writers of folk ragtime often simply mixed together themes of theirs in a random fashion, in structure loosely resembling the typical classic rag structure (introaabbaccdd.) good testimony of this are the legendary multiple takes of folk rags by sanford brunson campbell, recorded on acetates in 1947. they illustrate a performer who embellishes and improvises on basic themes, at times seeming as if he is making it all up as he goes along.
