Harmony Sweepstakes
From Wikipedia, the free encyclopedia
The Harmony Sweepstakes is a yearly competition that is open to 3-8-member a cappella groups across the country. Prior to 2007, the maximum group size allowed was a septet. The competition is organized by region. Each region produces one winner; the winners of each region compete in the national finals in San Francisco.[1] The 2006 National Champion was Hi-Fidelity.
