Ok, I NEED you to understand just how insane even ATTEMPTING this was for them.
1. Playing an instrument is difficult. Doing so in sync with others even more so. Don’t think I’m stepping on any toes saying that.
2. Dancing is difficult. Doing so in sync with others even more so. Still not controversial.
3. YOU AVOID, AT ALL COSTS, MOVING YOUR BODY WHILE PLAYING A WIND INSTRUMENT. To make the correct, pleasant sounds, you need to be in the correct form. And that form involves your ENTIRE body, even your legs when sitting down.
4. “oh, but I’ve seen marching bands before and-” MARCHING BANDS HAVE ENTIRE SCIENTIFIC FIELDS DEDICATED TO FIGURING OUT HOW TO MARCH WITH MINIMUM BREAKING OF PROPER FORM. A marching band tries to be as smooth as possible while moving, so as not to jar their instrument, mouth, neck, arms, torso, or anything else.These ladies and gentlemen are BOUNCING and still playing properly, what the FU-!
5. AND ANOTHER THING! Wind instruments and dancing BOTH make demands on your breathing, so the fact that they are dancing (making you breath faster for extra oxygen) AND playing wind instruments (making you effectively hold your breath) AT THE SAME TIME is HUGE. Their lungs must be MASSIVE.
