 A small playing chamber is inside the tower containing a wooden chimestand with fifteen pump handles that control the clappers inside the bells via steel wires.Each lever is marked with a musical note, which form an almost complete chromatic scale, ranging from low D to high G while missing low D-sharp and both F-naturals..This configuration of bells were cast such that it can play the university fight song “Illinois Loyalty” in the key of D-major.
