Harvard Din & Tonics (Musical group)

The Harvard Din & Tonics are Harvard University’s signature jazz a cappella singing group, Known around the world for their rich tradition of excellence in both music and performance. With a repertoire centered on the American jazz standards of the 1920s, 1930s, and 1940s, these Harvard scholars—who perform in white tie, tails, and lime green socks—have an enviable reputation for their impeccable musicality, snappy choreography, and hilarious antics.

The Dins have existed in several incarnations during their history, beginning as the Dunster Dunces in 1946. The Dunces performed around the Harvard campus until the 1960s, eventually leaving behind a treasury of barbershop and jazz arrangements that would later form the basis of the Din & Tonics’ repertoire.

Previously an all-male ensemble, the group admitted its first woman member in 2018, and a second in 2019.
