Sousa standardized the military march form in America, see below. His marches are typically marked by a "subdued" trio—as in "The Stars and Stripes Forever", where most of the performing band becomes subordinated to arguably the most famous piccolo obligato in all of music.[citation needed] Sousa's magnum opus, "The Stars and Stripes Forever" was adopted in 1987 as the national march of the United States.[1]
