People who play the cello are simply not good looking. Most cellists are in analysis which won't end until they can play a scale in tune or, in other words, never. Cellists wear sensible shoes and always bring their own lunch. Double bass players are almost completely harmless. Most have worked their way up through the ranks of a large moving company and are happy to have a secure job in a symphony orchestra or anywhere.
Harpists are gorgeous.
And they always know it. They often look good into their late eighties. Although rare as hen's teeth, male harpists are equally beautiful. Pianists in the symphony orchestra work the least and complain the most. They have unusually large egos and, because they can only play seated, also have the biggest butts.
