School choirs from across the area perform every December in Downtown Chattanooga.
It's part of an annual event called "Christmas at the Courthouse."
Central High School's choir was one of the groups that performed.
Martha Boutwell is the Choir Director at the school.
"We study music in terms of history of musical development, but also in terms of the magic of the season.
It's winter time and music that you hear around this holiday time of the year."
