Barbershoppers actively support community service projects and local charities, and contribute many man-hours singing for churches, schools, and hospitals. In addition, most of the organization's chapters stage at least one annual show, bringing featured quartets and choruses to the community.

Harmony Foundation is the Society’s charity. It actively guides all fund raising for the benefit of the Society. Its annual fund campaign supports special Society projects, including Directors College scholarships, Harmony Explosion Camps and the Heritage Hall Museum of Barbershop Harmony. The Foundation also guides the growth of an endowment program and oversees grant education and services for Society districts and chapters.

With such a wide range of activities to enjoy, it's easy to understand why society members tend toward long terms of membership. Although most men join for the music, most stay in the organization because of the strong, deep friendships they build by raising their voices in song with other "congenial men of good character."
