The diagram shows, in detail, the various steps involved in the construction of a violin by hand.
Starting with a thin piece of wood, the front and back parts of the violin (having identical shapes) are carved out separately using a saw, followed by constructing the f-holes on the front part using a cutting tool. Then, a bass bar is glued to the front part of the violin. The unshaped rib strips are heated using a heating tool to give them the desired shapes, which are then glued together with the front and back parts of the violin. Next, the structure containing the scroll and neck of the violin is constructed and attached to the main body of the violin. Subsequently, some additional parts are also attached to it, followed by adding finishing touches using a varnish. The violin is thus completed and ready to use.
In summary, the diagram provides a detailed procedure of constructing a violin manually and the various methods used to ultimately achieve the requisite shape and functionality of the same. It portrays the procedure of transforming a thin piece of wood into a fully-working musical instrument and the various smaller elements that a violin is made out of.
