Harmony Heritage, the Southern New England chapter of Harmony, Incorporated, an international organization of female a cappella singers specializing in the barbershop harmony style, will perform at 6 p.m. on Wednesday, June 21 and at 7 p.m. on Tuesday, July 18 at McCoy Stadium in Pawtucket.

The chorus is inviting female singers to join them for both performances. To join in, guests must attend two out of three of the chorus’s Tuesday night open rehearsals on either June 6, 13 or 20 from 7:15 to 7:45 p.m. Regular, open rehearsals take place on Tuesdays at St. Paul’s Episcopal Church at 50 Park Place in Pawtucket. More information can be found at the chorus’s website, www.harmonyheritage.org .

“We always enjoy bringing barbershop harmony to the community,” says Anne Diggle, chapter president. “The Harmony Heritage chorus looks forward every year to singing our country’s National Anthem at these games. We see it as a civic duty, and it is also just about the coolest thing we do!”

The Harmony Heritage chorus sings in the barbershop harmony style, which traces its musical roots back to the turn of the 20th century. Today, barbershop harmony singers not only celebrate the classics, but also put their own spin on contemporary songs as well.
