Accordions big and small
Adorn my muse's wall
How versatility meets nuanced flair
All from a bag of, well, hot air.
The hurdy-gurdy. Has three levels or layers of sound: The winding thingy "bows" the strings, which if I recall correctly has both 1. a harmonic drone as well as 2. an independent melodic function, and somewhere else there's a sort of percussive thing that gives a beat. Impressive construction sense, though I don't particularly care for the timbre.
