「空にはとどろ。号砲の。」(Sora ni Hato Doro. Gouhou no.)

A march is a musical genre and form designed to accompany orderly movement, most commonly military processions, parades, and ceremonial events. It is typically in duple meter (2/4 or 4/4) or compound duple (6/8), with a steady tempo that supports synchronized stepping. Classical and concert marches evolved a characteristic multi-strain structure: an introduction, two strains, a key-changing trio, a break strain ("dogfight"), and a final strain, often with a strong cadential "stinger." Instrumentation centers on winds and percussion—brass, woodwinds, snare and bass drums, and cymbals—producing a bright, projecting sonority suitable for outdoor performance. While the style is pan-European in origin, the late-19th- and early-20th-century "golden age" of the American march, led by John Philip Sousa, codified the concert march’s form, orchestration, and performance practice, influencing wind band music worldwide.
