The deer in our woods like drumming.

Of our six cats, most are indifferent, but Cougar (white and fuzzy) and Rainbow (the tabby) and Romeo (Black and white and fuzzy) all come and sit in my lap when I play the harp, and Cougar tries to help. But if I whistle, she bats me in the face till I stop (those high frequencies).

Both cats and dogs (we have two presently)aren't driven away by it. But it doesn't seem like they respond too much aside from the above mentioned; Of course there's almost always canned music playing if someone isn't making it. Maybe they are just too accustomed to it.
