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. Parade marching In parades, bands usually line up in a marching block composed of ranks and files. Each member tries to stay within his or her given rank and file, and to maintain even spacing with neighboring musicians. It is traditionally the responsibility of the people at the end of each rank and the front of each file to be in the correct location; this allows other band members to use them as a reference, also known as guiding. Band members also try to keep a constant pace or step size while marching in parade. Step sizes usually vary between 22 and 30 inches (56–76 cm) per stride. A step size of 22.5 inches is called an 8-to-5 step because the marcher covers five yards (about 4.6 m) in eight steps. A step size of 30 inches is called 6-to-5 because five yards are covered in six steps. Because yard lines on an American football field are five yards apart, exact 8-to-5 and 6-to-5 steps are most useful for field shows. A drum cadence, sometimes called a walk beat or street beat, is usually played when the band is marching, oftentimes alternating with a song, and is typically how a band keeps time while not playing music. Alternatively, a drum or rim shot may be given on the odd beats to keep the band in step. Between songs and cadences, a roll is usually given to indicate what beat in the measure the band is at. Cadence tempo varies from group to group. Street performances In Minnesota, Upstate New York, and Wisconsin, bands may perform on city streets with compact formation elements, sometimes referred to as a street show. These shows are judged using similar criteria as any other marching band competition. Elements of difficulty increase with street marching competitions because of the varying widths of streets in each community. Street marching is typical for bands who operate during the spring and early summer months. Typically, a band that performs in street marching competitions does
