I think from a folklorist standpoint, the traditional singer evolves from a community that is isolated so that a particular stylistic approach to a song is taken. I don't think of a traditional folksinger as being musically eclectic. The style comes from this community usually handed down generationally affecting vocal style, phrasing and aesthetic values regarding vocal tone and ornamentation.

I don't think everyone can be a traditional singer but everyone can sing their songs.
