oh, I hadn't thought of it that way. My perceived pun was because it's the weight of people on the stairs that will cause the unwanted cacaphony.

One or two persons' weight might be a sonata, but too much weight in too many places on the piano stairs - and you've got Downtown Disney near the Uva Bar.

For every job that must be done
There is an element of fun.
You find the fun and
snap! the job's a game.
