The West Lafayette Symphony Orchestra (WLSO) is a collaboration between the band and orchestra divisions of the high school music department. The ensemble exists in the second semester only, and performs at the ISSMA State Qualification Contest in late April.
The WLSO will rehearse during class times, as well as coordination rehearsals listed in the Event Calendar section. The WLSO is directed by Mr. Pettit, Mrs. Brooks, and Mrs. Letcher. The WLSO has made it to State Concert Finals in 2012, 2013, 2014 and 2016.
