The battery in any marching percussion setting consisits of the instruments that you see marching on the field. It's what most people think of when they think of marching percussion. It consists of a marching snare, which is much deeper and tuned much differently from a concert or set snare. The sound it gets sounds roughly like what a hardwood table would sound like if it had snares on the bottom. Then there are the tenors. Tenors have many, many names. Some derive from the number of drums that you have, i.e. quads, quints, sixes, squints, etc. Most people just call them tenors or toms though. Lastly are the basses. A battery can march any number up to 9 bass drums, and it stops at nine because the majority of marching percussion manufacturers only produce nine sizes. The avrage is from 4-6, though. The point of the bass drums is to make four people, playing four differntly toned drums, sound like one person. At BHS, we march 2 snares, one tenor, and 4 basses. The captain of the percussion section (battery and pit) is Nick Gleason. I'm also the webmaster here. Feel free to e-mail me with any questions.
