My nightmare of nightmares is being overdressed for a casual event - I've done it! You have to have a real sense of what you want to communicate.
Anything you strike, anything you shake or rattle, or just anything that can be picked up, and you can create a sound.
To say that an idea is fashionable is to say, I think, that is has been adulterated to a point where it is hardly an idea at all.
