A rumline or drum line is a section of percussion instruments usually played as part of a musical marching ensemble. Drumlines are usually incorporated into high school or college marching bands, drum and bugle corps or drum and lyre corps, indoor percussion ensembles, and pipe bands, but also can exist independent of these ensembles. The term battery is used to refer to a specific part of the drumline. The battery is the drum section that marches on the field as a group. The battery usually consists of snare drums, bass drums, tenor drums, and cymbals. Stationary percussion within a marching ensemble is called the front ensemble or pit. This also describes the area where those percussion instruments are set on the field, and also where to listen for tempo.
