Mechanics & Modes
How The Mechanical Wizardry Works
The Hurdy-Gurdy spins a rosin-coated wooden wheel against strings, acting like a continuous violin bow.
Tangent Keys slide wooden pegs against the melody strings to shorten vibrating length.
The Trompette (Chien / Dog) bridge rests loosely on a drone string: when the crank accelerates rapidly, string vibration forces the hammer to strike the soundboard in rhythmic pulses.
