Central Ohio Symphony is marking its ruby anniversary with an emotional and intense line-up of music.

The orchestra, based out of Delaware, is celebrating its 40th anniversary this year. The final concert in its season will be April 27. The concert will be at Gray Chapel (Auditorium) at Ohio Wesleyan University, 61 S. Sandusky Drive, Delaware.

During the 2018-19 concert season, the symphony has included special fanfares to mark the organization's anniversary.

The symphony was the third featured organization in ThisWeek Community News' "Hidden Gems around central Ohio" Facebook Live video series. Our previous stops included Anthony-Thomas Candy Co. and Akiba Arcade. 

In recent history, executive director Warren W. Hyer and conductor Jaime Morales-Matos have been at the symphony's helm, with more than 40 years of experience between the two. 

The orchestra includes more than 60 musicians.

The Gray Chapel (Auditorium) concert hall was built in 1893, according to the Central Ohio Symphony's website. The auditorium was built at a time when second-story windows were included behind the balcony seating, serving as natural lighting for the stage, Hyer said. 

The concert hall seats about 1,100 people, Hyer said.

Tickets for the April 27 concert cost $25 for general-admission seats, $20 for seniors, $6 for students and $4 for children. To purchase, go to centralohiosymphony.org or call the ticket office at 740-362-1799. Tickets also are available at the door.
