NORWAY — The Calderwood Consort’s Music for a Medieval Christmas, a program of period music concluding with a sing-along of traditional Christmas songs, will be performed at 2 p.m., Saturday, Dec. 17, at Christ Episcopal Church, 35 Paris St.

The program is in part based on an unusual telling of the Christmas story taken from the Wyclif Bible of 1380, the first English translation from the Latin, narrated in Middle English and accompanied by music from the 11th through the 17th centuries: Gregorian chants, secular and sacred motets sung and played on replica period instruments.

The second half of the program steps outside the Wyclif biblical setting with a variety of traditional and folk songs and instrumental dances sung and played on plucked and bowed strings, recorders, crumhorns and percussion, ending with an audience sing-along of favorite Christmas carols.

The Calderwood Consort has been performing early music throughout Maine since the mid-1970s. They’ve appeared at universities, colleges and churches throughout the state. They have performed in concert with the Boston Camerata and choral groups throughout Maine.

Members have included musicians with music degrees from Oxford University, The Royal Academy of Music, London, Bates College as well as early music groups in Cincinnati and St. Louis.

Program notes and text translations will be available and the consort will be in costume.
