One of my favorite genres in pop music, vocal group harmony, is better known as doo-wop. I appreciate doo-wop because of its simplicity, innocence, romance, novelty, and sound. Performed with or without instrumental accompaniment, it plays a vital part in the formation of rock ‘n’ roll. Its influence is enormous. Had it not been for a group like Frankie Lymon and the Teenagers, Michael Jackson (for one) might not ever have existed.
