A barbershop quartet is a group of four singers who sing music in the barbershop style, characterized by four-part harmony without instrumental accompaniment, or a cappella. The four voices are: the lead, the vocal part which typically carries the melody; a bass, the part which provides the bass line to the melody; a tenor, the part which harmonizes above the lead; and a baritone, the part that frequently completes the chord. The baritone normally sings just below the lead singer, sometimes just above as the harmony requires. Barbershop music is typified by close harmony— the upper three voices generally remain within one octave of each other.
The Barbershop Harmony Society, legally and historically named the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America, Inc. (SPEBSQSA), is the first of several organizations to promote and preserve barbershop music as an art form. Founded by Owen C. Cash and Rupert I. Hall in Tulsa, Oklahoma in 1938, the organization quickly grew, promoting barbershop harmony among men of all ages. As of 2014, just under 23,000 men in the United States and Canada were members of this organization whose focus is on a cappella music. The international headquarters was in Kenosha, Wisconsin for fifty years before moving to Nashville, Tennessee in 2007. In June 2018, the society announced it would allow women to join as full members.
