The 1954 attempt to define this music sounds good to me--as far as it goes. To the extent that a given folk presentation stays within the parameters of all that I did musically over the years, that defines folk music for moi well enough for most practical purposes.

Buy my issued recordings. Listen to 'em. There will be my views on this topic graphically depicted in the ear of the behearer.

Other than that, I don't seem to need these semantic exercises now.
