While military music, uniforms and flourishes mark pageantry from Barcelona to Beijing, two Americanizations of the marching band deserve notice. First is the repertoire and impact of American composer John Philip Sousa (“Stars and Stripes Forever,” etc.) on millions of parades to follow. Second, bands extend beyond the military and police to become major activities of high schools and colleges. Sports, civic events and pep rallies showcase them, and band members raise money to appear in nationally televised events like Macy’s Thanksgiving Day Parade or Bowl parades. The elaboration of the band (incorporating male and female students), includes drum majors and majorettes, flag teams and others to dazzle crowds.
