don't worry about dynamics, I've often omitted them by mistake and kinda yelled at the orchestra why they weren't following the decrescendo. Was rather funny. I mean it wasn't there so I was a jackass and said any good musician would of just felt it it and followed the conductor The brass guys said any good composer would of wrote them in. Then I threw my pencil trying to gauge his eye. Then we took a break. It was quite funny and we were all kinda joking around. I apologized for trying to blind the Trombone player and the trumpet player apologized on behalf of the violas as it was really all their fault all along.
