The weeks running up to the holidays make it difficult for people to concentrate on anything other than shopping and, well, more shopping. That’s why local classical music organizations know that it’s best to schedule their concerts for early in December.

Columbia Pro Cantare is doing its annual performance of Handel’s “Messiah” on Sundayat 7:30 p.m. at Jim Rouse Theatre at Wilde Lake.

Then, the Columbia Pro Cantare Chamber Singers perform their “A Christmas Noel” concert on Sunday, Dec.10, at 3 p.m. at Christ Episcopal Church in Columbia.

Howard County audiences rely on Columbia Pro Cantare to help put them in a holiday mood and generally encourage all of us to slow down and savor the music.

Its “Messiah” performance includes the Christmas section and selections from Parts II and III of Handel’s 18th-century choral masterpiece. Featured performers are soprano Amy Van Roekel, mezzo Leah Kaye Serr, tenor Charles Reid, baritone Steven Eddy and organist Henry Lowe.

“Our hearts and minds are more challenged than ever,” observed Columbia Pro Cantare music director Frances Motyca Dawson. “Music can ameliorate the sensory overload we are experiencing. Handel’s ‘Messiah’ has a powerful message for audiences, who find it comforting.”

Dawson knows that her faithful audience looks forward to hearing “Messiah” every year, noting that “people want to hear it, just as they want to hear Mozart’s ‘Requiem’ and Carl Orff’s ‘Carmina Burana.’”

Columbia Pro Cantare performs “Messiah” on Sunday at 7:30 p.m. at Jim Rouse Theatre at Wilde Lake, 5460 Trumpeter Road in Columbia. Tickets are $23, $20 for seniors and students, in advance; $2 more at the door.

There will be a pre-concert lecture by Ernest Liotti at 6:30 p.m.

The ensuing Dec. 10 program finds a smaller ensemble doing what Dawson termed “a varied program” of seasonal music spanning several centuries and encompassing both familiar and unfamiliar songs.
