It's long been known in the orchestra that each section of the orchestra seems to have a certain kind of personality -- collectively for the section, if it doesn't hold true for the entire orchestra.
Now I wonder, does this correspond with MBTI? Can we force it? I'll need some help, because I'm only really familiar with string orchestra.
I'll start us out:
Even though they don't play an actual instrument, a good conductor has to be innovative with musical interpretation but still be strict in implementation. They keep the entire orchestra on task, but they can also go on their own little 'power trips' if they're not careful.
