I know that flautist is just as correct as flutist when referring to a flute player. Still, it irks me whenever an announcer refers to a flutist as a flautist. We don't refer to trumpeters as traumpeters, nor do we call a tuba player a tauba player. We also don't call a drummer a percaussionist who plays the draums.
Classical music is sometimes perceived unfairly as pretentious. Much of it is actually quite accessible. Why not cater to that accessibility by calling a flutist a flutist?
