The Ohio State University Marching Band

The Ohio State University Marching Band (OSUMB) performs at Ohio State football games and other events during the fall semester. It is one of the few collegiate all-brass and percussion bands in the country, perhaps the largest of its type in the world. Its nickname is The Best Damn Band in the Land (TBDBITL).

Military training was an important part of the early curriculum at Ohio State, and a band was formed to provide music to the cadets for drills. Organized in 1878, the Marching Band was first organized as a fife and drum corps and was sponsored by the Military Department. In 1881, a stolen mouthpiece incident, which prevented the Marching Band from performing, led the Military Department to end support.

The band made national headlines in the summer of 2014 following the release of an internal investigation into the band's culture and reported incidents of hazing.

The Diamond Ohio logo, which is created by superimposing the I over the center of the H, and making the O's into pointed triangles, was first created by the OSUMB in the late 1930s. The band continues to use this formation today every home football game as the team entrance tunnel. The Ohio University Marching 110 has also used the Diamond Ohio logo since 1966 when director Gene Thrailkill designed a pregame set modeled after the Ohio State University Marching Band to give the newly reformed Marching 110 a symbol.
