I've written previously about my college orchestra director's rotational seating. Granted, as an orchestral musician, you get to play great pieces by stellar composers regardless of your chair placement.
Still, did I have a slight ego boost when the designation of Principal appeared next to my name on certain concert programs?
Yes, in all honesty. I know it shouldn't matter, but I never tired of the good musician implication that title carried. Vanity is ill-advised, but what if the title that elicits it is the result of your hard work and years of practice?
