Scotty Chappell was one of the true pioneers in the development of modern day competitive drum and bugle corps. His association with the Lieutenant Norman Prince senior corps of the Boston area, more popularly known far and wide as the Princemen, began in the 1930s. He was involved in the instrument changes that allowed music arrangements to become more sophisticated as the horns evolved from bugles, to piston bugles, to piston bugles with rotors or slides. He was also considered one of the best drum majors of all time. The Princemen were chosen the corps of the decade for the 1940s by the World Drum Corps Hall of Fame.
