legs completely straight while marching forwards, they also do so while marching backward, to preserve uniformity of style). Using peripheral vision to align oneself to formations or field markings is even more important during backward marching. Marking time When a band is not moving, the members may mark time, or march in place. The step used usually resembles the step that is used for marching forward, though mixing a high step mark time with a roll step march (or vice versa) produces an interesting visual effect. For a typical mark time, the foot is raised to the ankle bone of the opposite leg. The toe should not come off the ground and the knee should not come out much past the still-straight leg. Some bands mark time by bringing their feet up to their knee—known as high-mark time. Some bands practice marking time during concert arch with the toes coming off of the ground to give the marcher a greater sense of marching while standing still. The heel should hit the ground on the beat. Some bands forgo marking time and instead come to a complete halt when not marching. Traditionally, the drumline would put their feet in a V-shape and lift their feet fully off the ground a few inches. This is to avoid hitting the drums. Staying in step Even when marking time, it is considered good form for all band members to stay in step—that is, step with the same foot at the same time. A large majority of bands step off with, or start marching on, the left foot. Staying in step is generally easier when the band is playing music or when the drums are playing a marching cadence. When the band and percussion are not playing, rhythm may be maintained in a variety of ways: a drummer may play taps or rim shots, the drum major may clap or use a woodblock, a drum major or band member may vocalize a sharp syllable like "hit," "hut," or "dut," or band members may chant the military call of "left, left, left right left." Band members may count the steps of the move out loud to keep the entire band together. Typically, most moves consist of any number of steps that are a multiples of two or four, due to most marching band music being in even numbered time signatures. Even-numbered time signatures aid in staying
