In this seventh episode of Dr. Music we will be hearing examples of pieces that incorporate wordless choruses. The human voice is a musical instrument, and when composers use the human voice to simply sing syllables, it's an amazing effect. Whether the wordless chorus is unaccompanied or blended with other orchestral instruments, the richness of character from the acoustic voice always adds so much color to the music's tapestry. Featured musical examples will be everything from Rachmaninoff to the film composer John Williams!
