The Four Freshmen is a multiple Grammy-nominated American male vocal band quartet that blends open-harmony 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, trumpet, bass, and drums, among other instrumental configurations.

The group tours internationally to sold-out audiences and records jazz harmonies since its late '40s founding in the halls of the Jordan School of Music at Butler University (Indianapolis).
