There are several characteristics of doo-wop music, one of which is the unique range of voices. The typical ranges of voices in a doo-wop group are the lead singer, the falsetto/first tenor, second tenor, and a baritone singer. While falsetto was usually done as background, one group in particular, the Four Seasons, capitalized on their lead singer, Frankie Valli’s, amazing 3 and a half octave vocal range, making falsetto the lead voice. Another characteristic of doo-wop music is that it is usually very simple and easy to sing along to, which is one of the main factors leading to its success. Many people enjoyed it because they could participate in it, and recreate it themselves.
