Well, as fun as it was to create dissonance, I never did it when I had to act serious and play like I was supposed to.
One of my conductors in high school, a short, flamboyant, nerdy Jewish man, was often poked fun at behind his back, and I always felt terrible that a man who wanted to be serious and make good music would constantly have to stop and yell at the idiots who did that. I wanted to make pretty music myself, and in our private lessons he was quite wowed at my skills and knowledge of music, as well as the fact that I liked to listen to recordings of pieces I was going to perform.
In my senior year, when I helped out in the ensemble that had such students, the newest conductor noticed a difference in the expressions on my faces. She saw the happy, amused look on my face in the ensemble I was normally in, as well as the frustrated, annoyed look on my face in the band I helped out in.
