Sweet Adelines International Harmony Classic competitions

Harmony Classic is a women's barbershop competition for small and mid-sized choruses run by Sweet Adelines International as part of the organisation's annual convention since 2010. The results of the competition are as follows. For a full explanation of the scoring system, qualification process, awards and records, see Sweet Adelines International competition.

Qualification for the competition happens as part of the regional chorus competition. The five highest-scoring small (division A, 15-30 singers) and midsize (division, AA 31–60 singers) choruses across all regional competitions qualify directly for the Harmony Classic of the following year. With five choruses in each of the two divisions (A & AA) a total of 10 choruses compete in this competition each year. Only one chorus from a region may compete in each of the divisions and the previous year's winner may not compete in the same division again the following year. Furthermore, a chorus may not compete in both the main competition and also the Harmony Classic at the same year. A chorus may potentially qualify for both the main chorus competition as well as the Harmony Classic, but are only permitted to compete in one, thereby making a space available for the next highest qualifier to take their place at the other competition.
