The Hurdy-Gurdy
This is a cool thread, innit? Thanks, Dragnolias!
The hurdy-gurdy -- veille in France -- was the traditional instrument of the medeival troubadour. More recently, it has been used by some rock musicians, most notably Page and Plant (1995 tour) and Loreena McKennitt.
Even though it's a stringed instrument, the sound is like a combination between a bagpipe and an oboe. One hand turns a crank which operates the "drone" (single note) strings and there is a keyboard, played by the other hand, which plays the melody by striking like a piano, rather than plucking like a harpsichord.
I can't post a link, but if you do a Google (or whatever) search for hurdy gurdy mp3 you will find several samples available on the 'net.
