About a month ago, when I was at the band hall of the McMurry University, I forgot to take a picture of the quote above the entrance/exit. When we arrived I took several, but Saturday night after the midnight snack and more than 12 hours practice on Saturday (three 4 hour blocks) the instructor told the tuba players to get their instruments and "just" hold them for 3 minutes. Every time one arched his back or held the instrument to their bodies they all got a 20 second penalty. They hate this exercise, but the I'm sure the quote works here!
