Sociology and the band-geek

It is always interesting to watch people in a large group divide by personality. Without much variation personality and the role in the group correlate pretty well.

But, does the role determine the personality or the other way around? Or is it all just a big coincidence?

There is a personality to a Wind Ensemble and likewise to Orchestras.

Percussionists are the wild ones, the jokesters and party animals.
Flutes are used to getting their way. They have a tendency to consider themselves 'above' the rest.
Tuba players are happy.
French Horns are perfectionists.
Saxophones are the popular ones.

etc etc etc
(I could go on, but then you get into Orchestral social dynamics which changes it all around a bit too)

Now, are these attributes (stereotypes) simply some skewed view of the instrumental role? Or do the groups that take these people draw like types to them? Or is there a weeding out process that does this? Or is this all just hallucination?

There are other communities with similar dynamics but band seemed the most universal for showing it.
