Drum Corps International

Drum Corps International, colloquially known as DCI, is a non-profit global league of drum and bugle corps. Its slogan is "Marching Music's Major League," and since its inception in 1972, it has grown to operate North America's junior drum and bugle corps, for marchers between the age of 13 and 22 years. Its counterpart is DCA, which operates senior, or all-age, drum and bugle corps.
