The Newburyport Choral Society will launch its 80th annual winter concert at 2:30 p.m. Dec. 14 in Belleville Congregational Church, 300 High St. The society will perform Handel’s “Messiah,” under the baton of Gerald Weale, the choral society’s music director for 27 years. The program also will feature the voices of children who represent the future of choral singing. The Molin School Children’s Chorus, an after-school chorus of fourth- and fifth-grade students, will perform under the direction of Gina McKeown and join the Newburyport Choral Society in the popular “Patapan.” The society also will perform “Hymn to the Virgin,” by Benjamin Britten, and “O Magnum Mysterium,” by Morten Lauridsen. As always, the concert will include a professional orchestra and soloists, and audience members will be able to join the 120 voices of the society in singing familiar carols. Tickets are available online and at ticket outlets. Cost: $22 for adults; $20 for students and seniors; and $15 per ticket for parties of 10 or more. Tickets purchased at the door will cost $25 each.
