One year I pointed out the key signature, the formatas, and played the piece. The judges had to scramble to their seats and pencils. All three judges gave us a "1" but all they wrote on their sheets was about how I should have used my time, nothing about how the band played- not one word. I learned my lesson, so now I use the entire time, and receive great commits about how well I coved the piece.
Every five years or so UIL puts a terrible piece in front of us that is not musical, and is poorly written, so you better know how to cover a piece when that comes around.
