One of our two public radio stations up here (98.3 KNBA) is native owned/run so they have several radio shows of both modern and traditional Native songs, Robert Mirabeau and such.
I've always wondered, but never asked, if the "heeeey-ya hey-ya" so common in Plains Indian songs is an actual "word" or a vocal music sound or "melodic noise" to go with the drum rhythm and dancing.
Anybody know?
I assume it's different than as used by Outkast.
