While playing music during a field show, the band makes a series of formations, called drill, on the field, which may be pictures, geometric shapes, curvilinear designs, or blocks of musicians, although sometimes it may be pure abstract designs using no specific form.

Typically, each band member has an assigned position in each formation. In many show bands and most drum corps, these positions are illustrated in a handheld booklet called a drill book. Drill books, or drill charts, show where each person stands during each set of the show. The drill charts include yard lines and hashes as they would be on an actual football field, which shows the band members where to stand in relation to the yard lines and hashes. There are many ways of getting from one formation to the next:

* each member can move independently – this is called scattering or "scatter drill"
* all the members can move together without deforming the picture – this is called floating
* the members can stay in their lines and arcs, but slowly deform the picture – this is sometimes called rotating or expanding
* the members can break into ranks or squads, each of which performs a maneuver (such as a follow-the-leader) which may or may not be scripted – an unscripted move is sometimes called a rank option
* each member may have a specifically scripted move to perform – in these cases, the desired visual effect is often the move itself and not the ending formation

Many bands use a combination of the above techniques, sometimes adding dance choreography that is done in place or while marching. Players may point the bells of their instruments in the direction they are moving, or slide (also called traverse) with all the bells facing in the same direction. Bands that march in time with the music typically also synchronize the direction of individuals' turns, and try to maintain even spacing between individuals in formations (called intervals). Sometimes bands will specifically have wind players turn their instruments away from the audience in order to emphasize the dynamics of the music.

Auxiliaries can also add to the visual effect. Backdrops and props ("scrims") may be used on the field that fit the theme of the show or the music being performed. In comedic shows, particularly for university bands, an announcer may read jokes or a funny script between songs; formations that are words or pictures (or the songs themselves) may serve as punch lines.
