United States Military Cadences are sung in either a marching or running formation of soldiers/cadets. They are sung first by a commander or someone else in the formation that is then repeated by rest of the soldiers in the fomation. Once the commander is finished with one line the others then repeat that same line. The cadence is sung so that there is a lightly upped tone in the voice of Soldiers when the left foot hits the ground. (i.e. HERE we GO again, SAME old STUFF again MARCHING down THE avenue SAME old STUFF and WELL be THROUGH.)
