Geometry in marching band. Marching band isn’t all about playing music and counting. In marching band you have drill, which is a picture representation of all the different shapes and forms the band makes as a whole. There is surface area involved because you need to know the dimensions of the stadium. Here is a website I used

The Math of Marching. I have another example of how there is math in marching. Without the influence of mathematics a marching show has no tempo, rhythm or general effect. Like elbows must be bent at a 90 degree angle and instruments should be held at a 45 degree angle. Without math a marching band could not exist because there’s no where to pinpoint which member goes where, make formations and pay music while doing so.
