Abstract: A violin tuning arrangement and method is provided in which the bridge of the violin may be moved longitudinally along the violin by a mechanical mechanism which will automatically bring the bridge to predetermined points where a predetermined change in sound will be emitted by the violin. The mechanical arrangement includes two tuning wheels which are journaled in the sides of bridge holding brackets and may be moved discreet distances along the rack on the surface of the violin to change the tone or tuning of such violin. Discreet arrangements of teeth or detentes are provided so that the tuning wheel will tend to automatically cease movement at a point which provides a desired tuning of a violin.
