Take a familiar refrain. Add enthusiastic choruses. Gather masses of people to lift their voices in song. All these elements help ensure that Chorus Austin’s 27th annual “Sing-It-Yourself Messiah” has something to help everyone get the holiday season started on the right note.

The concert features popular arias and choruses from Handel’s beloved oratorio that bring together Chorus Austin singers, orchestra members and soloists with an enthusiastic audience. This one-performance-only concert is set for 2 p.m. Saturday, Dec. 3, at St. Matthew’s Episcopal Church, 8134 Mesa Dr.

“For Unto Us a Child Is Born,” “And the Glory of the Lord,” “O Thou That Tellest Good Tidings to Zion,” “All We Like Sheep,” “Hallelujah” and other familiar selections will be performed by the 180 voices of Chorus Austin’s Symphonic Chorus under the baton of Chorus Austin Artistic Director Ryan Heller. Audience members are encouraged to bring their own copies of Messiah and sing along during the choruses. A limited number of Messiah scores may be borrowed at the door.

Soloists for the afternoon are Julia Taylor, soprano; Cindy Sadler, alto; Steven Brennfleck, tenor; and Kerry Wilkerson, bass. The program, with a variety of chorus selections and solos, includes all of Part I, traditionally called the “Christmas portion,” plus selections from Parts II and III including “Surely He Hath Borne Our Griefs, “The Lord Gave the Word,” “Since By Man Came Death,” “I Know That My Redeemer Liveth,” “The Trumpet Shall Sound,” “Worthy Is the Lamb That Was Slain” and “Amen.”
