It's no secret that mathematics and music go hand in hand. Frequencies, subdivisions, tempos; it all comes back to mathematics. One of my favorite intersections of mathematics and music is predominantly an American activity: drum corps. A drum corps, for those of you who are unfamiliar with this activity, consists of 100 or so members. There are trumpets, mellophones, baritones, tubas, a large percussion section, and a color guard. These members run around the field playing extremely difficult and entertaining music. The color guard tosses rifles into the air at heights of around 25 feet an catches them with ease! It's a huge step up from the traditional marching band; it's faster, louder, requires true athleticism, and it draws crowds in by the thousands night after night in the summer.
The most mathematical part about drum corps, however, is the drill, or the sets of movements that all the members make. Visual artists from each corps draw inspiration from geometry, especially symmetry. There have been some truly phenomenal shows with delightfully mathematical drill. I'll share some links below to some of my favorites!
Here are a few really cool drum corps shows y'all should check out:
