Barbershop Harmony Society

The Barbershop Harmony Society (BHS), historically known as the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America, Inc. (SPEBSQSA), is a nonprofit organization dedicated to promoting and preserving barbershop music as an art form. Founded in 1938 by Owen C. Cash and Rupert I. Hall in Tulsa, Oklahoma, it has grown to become a leading organization in the field of a cappella barbershop harmony.

Background and Mission

The Society was established with the primary goal of preserving and promoting barbershop quartet singing. Over the years, it has expanded its mission to include education, performance, and community outreach. BHS operates under the motto of bringing people together in harmony and fellowship to enrich lives through singing.

Programs and Activities

• Music Education and Publishing: BHS offers various educational materials and workshops to improve barbershop singing techniques. It also maintains an extensive sheet music repository known as the Old Songs Library, containing over 100,000 titles.

• Performances and Competitions: The Society organizes annual international and district-level contests for barbershop choruses and quartets. Winning quartets are considered champions forever and do not compete again, while choruses must sit out for two years before recompeting.

• Community Outreach: Through its programs and partnerships, BHS aims to extend the reach of barbershop harmony globally, fostering community engagement and musical development.

Governance and Membership

BHS is governed by an elected board of directors and supported by professional staff. As of recent years, the organization has allowed women to join as full members, with chapters deciding their membership composition. Previously, women could join as associates.
