The "Pride of the Irish" is the instrumental musical ambassador for Cathedral High School.
With nearly 120 musicians and guard members each year, the Pride of the Irish marching band continues to entertain crowds at football games, basketball games, and on stage. Cathedral Band has received Division I ratings in music contests across the state. The band traveled to and performed in Toronto, Canada in 1998; the St. Patrick's Day Parade in Dublin, Ireland in 2000 and 2008; the King Kamehameha Parade in Honolulu, Hawaii in 2002; on board the Music on the Seas Royal Caribbean cruise in 2004; was on national TV on November 27, 2005, in the Hollywood Christmas Parade; performed at Band Days at Purdue University (2009 and 2012) and University of Cincinnati (2010); and in the Magic Music Days parade in Disney World, Orlando, Florida in 2010. In 2012, the band returned to Hawaii to perform on Memorial Day at the USS Missouri Battleship, and at the veterans' resort of Hale Koa.
All band students also participate in Concert Band, Pep Band, and ISSMA District Solo and Ensemble Contest. The Concert Band also performs at two end-of-semester concerts, and at the ISSMA District Organizational Contest. Our Pep Band brings spirit, enthusiasm, and fun to six Cathedral varsity basketball games. Many of our students also participate in Jazz Band, and various percussion, woodwind, and brass ensembles. Students have the opportunity to audition for and participate in the IMEA Honor Band, Indiana All-State Band, Butler University All-Star Honor Band, Ball State High School Honor Band, and the Indiana All-Star Marching Band.
