Why tuples use parentheses ()'s instead of something else like <>'s?

I'll give you the Bilbao Guggenheim, which (at least in the exterior 
pictures I can find) is a very attractive building, but here in 
Seattle we must deal with the giant eyesore that is Gehry's Experience 
Music Project, which (at least to my eyes) looks like a monstrous pile 
of architectural rubbish.  I can appreciate Gehry's attempts to get 
away from the tyranny of the straight line, and even with the EMP 
there's certain details which turned out well, but the overall effect 
is that of an overturned garbage pail.
