The Mount View Chamber Singers of Mount View High School in Thorndike opens the 30th annual edition of Carols in the Round on Dec. 2; the holiday concert tour runs into mid-December. Admission to the concerts is free, although donations for tour expenses are welcome.

The Carols in the Round concert gets its name from its format. Students in the four voice parts surround the audience on all four sides, singing a cappella holiday music. The singers, using candles to illuminate their music, slowly shift around the room during the course of each concert.

In past years the group of 20 high school students presented their music to many people and many cultures. Funding for tours is raised in part from the sales from the CDs recorded by the group.

Performances on the 2021 tour are: Thursday, Dec. 2, at 7 p.m. at Freedom Congregational Church; Tuesday, Dec. 7, at 7 p.m. at Kennebec Valley Baptist Church, Waterville; Thursday, Dec. 9, at 7 p.m. at John Street United Methodist Church, Camden; Friday, Dec. 10, at 7 p.m. at First Church, Belfast; Saturday, Dec. 11, at 4 p.m. at Old Town United Baptist Church, and 7 p.m. at Knox Ridge Baptist Church; Monday, Dec. 13, at 7 p.m. at Chestnut Street Baptist Church, Camden; Wednesday, Dec. 15, at 7 p.m. at Liberty Baptist Church; Friday, Dec. 17, at 7 p.m. at Stockton Springs Community Church; and Saturday, Dec.18, at 4 p.m. at Hammond Street Congregational Church in Bangor.
