The Gamma Delta chapter of Phi Mu Alpha Sinfonia was founded when the Murray Mens’ Music Club wrote a check to become a chapter of Phi Mu Alpha Sinfonia, and this check bounced. The men decided to create a show called Campus Lights. Just by the success with which it was met that first year (1938) the men of Gamma Delta decided to make it an annual show. The first performance for Campus Lights was held on April 19th, 1938. The proceeds went to pay for the bounced check to the National Fraternity and then the Gamma Delta Chapter of Phi Mu Alpha Sinfonia was born on May 15th, 1938.

Gamma Delta is home to over 1,000 Sinfonians around the United States.
