Designed so that it fits around the body of the tubist and is supported by the left shoulder, the sousaphone may be readily played while being carried. The instrument is named after American bandmaster and composer John Philip Sousa, who popularized its use in his band. The Sousaphone was developed in the 1890s by C.G. Conn at the request of John Philip Sousa, who was unhappy with the hélicons used at that time by the United States Marine Band.
