The Sonora Bach Festival will host a Baroque Singalong — featuring choral music from the time of Bach, Vivaldi and Handel — at 2 p.m. Saturday in Columbia.

The festival is celebrating its 40th year and will host events throughout the month of October.

At Saturday’s singalong, the music is not rehearsed or conducted. Instead, it’s led by area music leaders who aim to keep the group together. This year’s leaders include Daryl Hollinger, John Carter and Barbara Broad. Accompanists for the event will be Dorothy Woodford-Arndt, Diane Day and Gail Johnson.

Last year’s singalong, featuring just the music of Bach, was a first for the festival.

“The event was so successful we decided to offer it again,” said Broad, the Groveland resident who initiated the program. “This year, however, we are broadening the repertoire to include music of other Baroque composers. Bach’s music is so profound and sophisticated that it can be very difficult to perform so we are aiming for music that people know or that, for the most part, can be read easily.”

This year’s music will include choruses by Handel, Vivaldi, Buxtehude and Kuhnau. From Handel’s “Messiah” will be “And the Glory of the Lord,” “Lift Up Your Heads,” and “Hallelujah.” Included to give a broader perspective of Handel’s creative output is a chorus from his “Ode to St. Cecilia’s Day,” and a duet from his “Chandos Anthem No. 4.” Antonio Vivaldi’s “Gloria” will be represented by its first two choruses and its last. Dietrich Buxtehude’s chorale cantata of the Christmas carol, “In Dulci Jubilo,” and Kuhnau’s cantata “To Us a Child Is Born” will also be featured.

Among compositions by Bach will be excerpts from “Cantata No. 4,” “Magnificat,” “B Minor Mass,” his harmonization’s of hymn tunes, and even some arrangements by Ward Swingle of The Swingle Singers fame.

The singalong will be held in Columbia at the Church of the 49ers.

“The acoustics, piano, parking and lighting are good at the church,” said John Carter, a committee member for the Baroque Singalong. “Add to that great music from Bach’s time and we have the makings for a wonderful afternoon.”

Musicians of all types, including youth and instrumentalists, are encouraged to attend. Listeners are also invited enjoy the performance.

Popular music singalongs have been a part of the American musical landscape for centuries. However, singalongs of classical music are relatively new. The most well known, the “Messiah Singalong,” which started in the 1960s in New York, began a craze of seasonal singalongs that are now found in cities both large and small.

“Singalongs give singers an occasional opportunity to experience choral music when they are not able to join a chorus or when their chorus is not able to perform the choral works requiring lots of strong singers,” Broad said. “We hope many people come out to enjoy this opportunity.”

Admission for singers or listeners is $5. Tickets are available online at sonorabach.org, by calling (209) 536-6330 or at the door.
