Founded by Colonel Charles Gerard Conn in the late 1800s, the C.G. Conn brand has been a staple in musical instrument manufacturing ever since. In fact, C.G. Conn himself developed the first American-made cornet. From there, business flourished. Specializing in top-quality band instruments and accessories, C.G. Conn places an especially large focus on school bands nationwide – the brand even hosted the first National Band Contest in Chicago.
