The Advisor Advises

In my experience, an easy conversation starter for any 'cocktail party' type of function is to ask the individual with whom you are pursuing a serious conversation, "so have you heard of any new collective nouns lately?" Collective nouns are most commonly used to describe groups of animals, but as a frequenter (is that a word?) of choir-related functions, I have been inclined to come up with my own list of collective nouns for voice parts. I didn't necessarily make these up on my own, but I have become rather attached to them.
