The Marching 110 is open to any students enrolled at Ohio University. Music Majors make up less then 20% of the 225-member band, and the remaining students represent a broad range of majors from all over campus. The Marching 110 training week begins in the fall, one week prior to the start of fall classes. The week begins with incoming member training on the first two days, followed by the return of upperclassmen to training week the next. On the evening of the third day, music and marching auditions are held. That night, membership information is posted. The Marching 110's directors choose 176 individuals for the pregame block, and 192 for the halftime block and additional members to make up the 225-member organization.
