Luthier

A luthier (/ˈluːtiər/ LOO-ti-ər) is someone who builds or repairs string instruments generally consisting of a neck and a sound box. The word "luthier" comes from the French word , which means lute. A luthier was originally a maker of lutes, but the term now includes makers of stringed instruments such as the violin or classical guitar. A luthier does not make harps or pianos, as these require different skills and construction methods because their strings are secured to a frame.

The craft of making string instruments, or lutherie (sometimes spelled luthiery), is commonly divided into two main categories: makers of stringed instruments that are plucked or strummed, and those that are bowed. Since bowed instruments require a bow, the second category includes a subtype known as a bow maker or archetier. Luthiers may also teach string-instrument making, either through apprenticeship or formal classroom instruction.
