Arts on the Square presents the Harrisburg Choral Society and the Sanctuary Choir of Market Square Presbyterian Churchin “Choral Masterworks” on Sunday, May 21, at 4:00 p.m. at Market Square Church, 20 S. Second St., Harrisburg.

Dr. Kyle Zeuch, music director of the Choral Society, will conduct. Tyler A. Canonico, minister of music at Market Square Church and artistic director of Arts on the Square, will be organist.
