It depends on the guys.... here's what I think instruments represent when it comes to guy.
A. Percussion: They're obnoxious and rather monotone when played right sound really cool.
B. Bassoon: A bassoon is very tempermental and if you touch it wrong it'll start to growl. (My bassoon growls a lot...) Also, it can be loud and obnoxious but when played just right makes beautiful music. Not to mention they're very sensitive.
C. Tube: Big, bulky and in your face. Tubas are caucky and think they're all that. A tuba's best buddy is a piccolo. (Hey, what can I say? Us little guys gotta stick with the big boys or people try and shove us around)
D. Piccolos: Virtually indestructable but if you talk to them wrong they'll shatter. Of course they're also caucky and love to stick with the tubas. Don't step on them or they'll break. Also, if you anger them they'll start to scream, and no one wants that.
E. Trumpets: The instruments who beleive they rule the world. Trumpets are fairly over-all stable instruments but tend to be rather sarcastic.
F.Oboe: A shy instrument. They're easy to push around but don't shove to hard or they'll pull out their reeds and scream. They can't squeak like a single reed, but they sure can be loud when needed.
G. Clarinet:They may seem shy and emo until you get in their faces. Touch them wrong and they'll squeak in your face.
H. Saxiphone: yet another caucky instrument. They're all in your face and generally fun to be with. They love to be around people and die for attention.
I know I know... there're other instruments but those're some of the ones I could add personalities to. So tell me, what do you think?
