Marching Band is one of the most popular activities at Oakdale High School. Students register for Marching Band in the fall semester of their class schedule. The band performs at parades, football games, community events, and band competitions including the Tournament of Bands Chapter 5 Championships. The band practices after school or in the evening, and performs on most Saturdays in the fall. Summer practices include Band Camp and practices in August in preparation for early performances. All students are required to attend Band Camp in August. A detailed schedule and the student fee structure will be compiled by the Band Boosters and distributed in the near future.

Color Guard (Marching Band Front) is an important part of the Marching Band, and enhances the visual performance of the Marching Band proper. Color Guard is a powerful and moving art form that combines dance with the choreographed spinning of flags, rifles, and sabres. The Color Guard class meets during the fall semester in block 5, then becomes an extracurricular activity for the Spring semester. The Color Guard is required to attend all Marching Band practices, including a two-week camp prior to the start of the school year, after school rehearsals, Varsity football games, and all scheduled Saturday rehearsals and competitions.

Concert Band is the curricular band which meets daily as a regularly scheduled class in the Spring semester. This ensemble performs at concerts and other musical functions. Concert Band is open to 9th to 12th grade students who have achieved a reasonable degree of proficiency on a woodwind, brass, or percussion instrument. Emphasis will be placed on basic skills and theory, as well as developing an appreciation for canonical Wind Band repertoire.

Indoor Guard is an extra-curricular Winter activity for students interested in competition. Each year a unique show is designed and choreographed using elements of body movement and dance alongside flag, rifle, and sabre routines. This group competes along with drumline at local, state, and regional events from January through early April. There is a participation fee and audition.
