The Barbershop Harmony Society (BHS) organizes the International Convention — the world’s premier celebration of barbershop harmony featuring international quartet and chorus competitions, music education, and the legendary Harmony Marketplace. The 2026 edition runs June 28–July 5 at The Dome at America’s Center in St. Louis, Missouri.

Attendees come from across the United States and dozens of countries worldwide, representing competing quartets and choruses, chapter administrators, music directors, vocal coaches, music educators, and devoted harmony enthusiasts.

The 2026 convention draws 250+ exhibiting organizations filling the Harmony Marketplace with sheet music publishers, instrument vendors, vocal health brands, performance apparel companies, and music technology providers. No other choral arts event concentrates more passionate music buyers in one place.
