The Midwest City High School Band is a 120-135 member band under the direction of Head Band Director John Davis and Assistant Band Director Mark Hensley. The marching band consists of three drum majors, a complete percussion sideline ensemble, a full field band, and a full drumline. In 2012, a new band room was added on to help hold two separate bands and ensembles during different time periods, and to help with the number of students in the program. During this period, the band received what is now the current band uniforms, along with more funding towards the band program itself. After the football season is over, the band switches from marching season into what is known as "Concert Season." Each year, the band becomes divided into two bands: the Symphonic Band and the Wind Ensemble. Each competes in the OSSAA state concert band contest held in April of each year. Both bands also perform in the Winter Concert in December, and in the Spring Concert in May of each year. The students in band at the feeder schools Monroney Middle School and Jarmen Middle School, along with some transfer students from different schools and districts, helped make the school's band program over the years, especially when Mid-Del made Jr. High schools into Middle Schools and moved ninth grade to high school, adding on to the number of students in the band program starting in 2007. This program also contains two jazz ensembles, "The Beginning Jazz Band," and the more collegiate "The Advance Jazz Band," both under the direction of Mark Hensley, who has directed the Ensembles since he began working at Midwest City High School in 2002.
