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 in step because they assign odd-numbered counts to the left foot, and even-numbered counts to the right foot. If a band member is on the wrong foot, for instance, odd on the right foot and even on the left, this is referred to as being "out of step". When a band member is completely off tempo, it is referred to as being "out of phase".
