A reader sent me a YouTube video of Doc Watson singing “Tom Dooley,” which I post above. Do not be fooled by the major key and the peppy tempo. Listen to his rather flat, undemonstrative voice. This is a traditional approach to folk music. He is concerned with presenting the song, not himself. Now listen to the folk-pop singer, Eva Cassidy, singing “Autumn Leaves” below. She is much more into displaying her personal take on the song – her song “stylings.” I am not taking a stand for or against this approach, merely pointing out that this is a key difference between traditional folk music and modern popular music.
