"The Fight Song" is the fight song of the university. The song was composed in 1919 by WSU student Phyllis Sayles with fellow student Zella Melcher penning the lyrics. In 2019, the CMB celebrated the 100th anniversary of the fight song by premiering a new version titled "Win the Day". It retains the same structure as the original with modernized composition. It is now the standard version of the fight song used by the band.
"Washington, My Washington" is the alma mater of the university. It was composed by James DeForest Cline in 1914 for a pep contest, and was adopted by the university in 1919 to be the alma mater. The version in use currently is an arrangement by past CMB director, Troy Bennefield.
The CMB plays many songs and "shorts" to get the crowd excited. The most common are:
The CMB performs a new halftime show for every home football game. This results in approximately six different shows for the CMB every year. The band also performs a halftime show at select away games and bowl games. The following list consists of some of the shows the CMB has performed for halftime.
The WSU Marching Band Championships is an independent, annual high school marching band competition hosted by the CMB. Bands from primarily eastern Washington and northern Idaho compete in a modern two-round competition format, consisting of prelims and finals. The festival is coordinated by the CMB, and was started in 2015 to serve high school marching bands in the region. The CMB performs as an exhibition group at this event.
