"Why didn’t Ellington consider his music jazz?"

Kathryn Jean Lopez asks Terry Teachout, who says:

His problem was specifically with the word “jazz,” which for his generation (he was born in 1899) still had strongly sexual connotations. Ellington believed that such ostensibly vulgar labels would prevent jazz from ever being taken seriously by artists, critics, and scholars, so he tried to come up with a different way of referring to the music. At one point, the label he preferred was “Negro folk music.” Needless to say, it never caught on.

Here's Teachout's new book "Duke: A Life of Duke Ellington," which contains the sentence — Teachout's second favorite of his sentences, he says — “He talked not to explain himself but to conceal himself.”
