From 1880 until his death, he focused exclusively on conducting and the writing of marches. He eventually rejoined the Marine Band and served there for 12 years as director. On leaving the Marine Band, Sousa organized his own band. He toured Europe and Australia and developed the sousaphone, a large brass instrument similar to the tuba.
