The Drumline consists of percussion instruments which can be categorized into Battery or Pit. Battery percussionists march on the field alongside with both the Band and Color Guard while Pit percussionists stay in front of the field. Like Color Guard, Drumline members learn a show different from the one in first semester and compete at Drumline tournaments throughout second semester. Battery instruments consist Cymbals, Snare, Tenor, and Bass Drums. Pit instruments consist of marimbas, xylophones, vibraphones, and several other percussion instruments. Together, both Battery and Pit provide The Royal Wilson Marching Alliance an invaluable element for performances.

     For the first time in Wilson's history, a Mallet Ensemble performance group was assembled with only four players. Not only does the mallet ensemble perform with the entire Drumline, but perform a separate show to compete with other percussion ensemble groups. This year, their show is entitled, "Flight of the Bumblebee."
