A Dictionary of Music and Musicians/Bridge
BRIDGE. The strings on the instruments of the violin tribe are stretched over a small piece of wood called the bridge, which transmits their vibrations to the body of the instrument. The shape and details of the bridge, as finally fixed upon by Stradivari, cannot be altered in any single respect without injury to the tone of the instrument.Soundpost. The thickness is of the greatest importance, for if too thick, it will not readily transmit the vibrations of the strings. The left foot must stand exactly over the middle of the bass-bar, and both feet must be at an equal distance from the f-holes.
