In the 'Motivation: Why do we do it?' thread, a few fellow bass players described themselves as introverts... and it got me thinking. In my daily life, I am largely an extrovert. I consider myself social and gregarious. However, onstage, I MUCH prefer the bass space; hanging in the back, laying down the groove, and supporting the band. Occasionally, I am asked to play lead guitar or sing. I'm happy to do it because I love music & performing. But I find it adds a little anxiety, as it puts me more 'out front'. So my question is, is there an overall tendency for bassists to be more introverted and guitarists/singers to be more extroverted? (Notice I said 'tendency' because there are always exceptions). How would you describe YOUR personality? Do you think your personality-type played a role in choosing your instrument?
