Re:Leeneia, are you saying that Burleigh, a black singer and composer, didn't know how to write and sing the dialect he knew?"

No, I'm saying that there mere 26 letters of our alphabet don't begin to cover the wide and subtle range of pronunciations of English around the world. If we really attempted to convey all those differences in print, many people would stop reading.

If a singer really feels respect for another group's dialect, then the singer ought to listen to it. Print will never do the job.
