Bill: as you know, Baby Dodds used to tune his drums. Maybe you COULD tune
your washboard - got a hammer? (unless it's one of those glass ones......)
On a more serious note, washboardists might be interested to know that in
sunny southern Portugal houses are still being built with integral
washboards - yes, really - affixed to the outside of the house, next to a
water tap. A lot cheaper than a washing machine, and very
environmentally-friendly! As they are made of concrete, I have never tried
playing one, so cannot comment on their pitch.

in Chicago, key of F-sharp)
