The Hurdy-Gurdy: A Violin Played with a Crank
Most stringed instruments need a bow or a pluck to make a sound. The hurdy-gurdy does it with a crank. This old instrument has been played in Europe for many centuries, and some musicians still play it at folk festivals today.
Inside the wooden body is a wheel, rubbed with a sticky substance called rosin. When the player turns the crank with the right hand, the wheel spins and rubs against the strings. It works a little like a bow that never runs out of room to move. The sound can go on and on without a break, which is hard to do with a bow.
The left hand plays a row of wooden keys. Each key pushes a small wedge against a melody string, which makes that string shorter and raises its note, just as a finger does on a violin. Other strings, called drone strings, are not pressed by any key. They sing one steady note underneath the tune, a bit like the constant hum of a bagpipe.
Some players give the crank a quick jerk to make a buzzing beat. This adds a rhythm that gets feet tapping. With a melody, a drone, and a beat all coming from one instrument, a single player can sound like a small band.
