Barbershop Quartet Preservation Association

Started over 25 years ago, the Barbershop Quartet Preservation Association (BQPA) is an association of amateur singers of all ages of good character who wish to share the joy of Barbershop Quartet singing. We are dedicated to the preservation of this great American-born musical art form. Our collective purpose is to pursue the joy of barbershop quartet singing for our own pleasure, to share this music with our communities and to preserve the art form by attracting other singers. BQPA’s twice annual festivals have experienced impressive growth in recent years.

Association of International Seniors Quartet Champions

When AISQC was organized in 1987, its expressed purpose was “to provide a fraternal organization for Seniors Quartet Champions and to encourage mature members of SPEBSQSA to sing in seniors quartets.”

A seniors quartet, as defined for contest purposes, is a group in which no member is younger than 55 and whose members’ ages total at least 240. Currently, there are 60 plus members in AISQC representing several districts.
