The Four Freshmen is an American male vocal band quartet that blends open-harmonic jazz arrangements with the big band vocal group sounds of The Modernaires (Glenn Miller), The Pied Pipers (Tommy Dorsey), and The Mel-Tones (Artie Shaw), founded in the barbershop tradition. The Four Freshmen is considered a vocal band because the singers accompany themselves on guitar, horns, bass, and drums, among other instrumental configurations.
