aaaack! I just noticed I had typed vocal "chords" instead of vocal "cords" several times. These days, vocal cords are now referred to as vocal folds, as Uilleand did. Good points about teachers, Uilleand. A bad coach can ruin your voice. I know of a mezzo soprano in my town who now travels twice a month two states away to a teacher because the last teacher she had almost ruined her voice.
