The classics of John Phillip Sousa and similar composers are still popular, but marching band music has expanded far beyond the old standards to include anything from Broadway show tunes to classic rock and contemporary pop. An excellent source for marching band sheet music is found on J.W. Pepper's website.
Marching band music today is divided into several categories. The main categories are field music, stands and pep band, parade music, and drum line. Within these main categories are up to a dozen subcategories. The parade music category provides more than 1,500 titles, including Sousa classics, Disney tunes, Broadway show tunes, and pop and rock classics. Many marching band parade programs include music from a variety of genres. During the course of a typical parade, a marching band may perform Sousa's "Stars and Stripes Forever" followed by Chicago's "25 or 6 to 4," something from Mary J. Blige or Earth, Wind & Fire, and then a rousing movie theme.
The various categories and search features of the J.W. Pepper site allow the band director, instructor or music programmer to select music or arrangements that are appropriate to the event, audience and skill level of the band. Searches can also be conducted by composer or original recording artist.
