Whew! I was proud of my little collection, but after seeing these lists, I'm getting the urge to go looking again. My wife and I have , let's see,
Three pianos (one new baby grand - hers.)
an electric piano (NOT a synthesizer)
two string basses
a mountain dulcimer
a tenor banjo
three guitars - a six-string, a four-string tenor, and perhaps the only eight-string tenor in captivity (I've never seen or heard of another one)
a soprano recorder
a penny whistle
a plastic flute-o-phone - like Helen's musette, my beginning instrument.
a button concertina
four or five kazoos
and yes, me too, a nose flute.
