Bow maker

A bow maker is a person who builds, repairs, and restores ancient or modern bows for instruments of the violin family. These include violins, violas, cellos, double basses, viola d'amore, viola da gamba, etc.

The French word for bowmaker (bow maker) is archetier for one who makes bows of the string family of instruments such as violin, viola, cello and double bass. Root of the word comes from archet—pronounced [aʁʃɛ]—the bow.

A bow maker typically uses between 150 and 200 hairs from the tail of a horse for a violin bow. Bows for other members of the violin family typically have a wider ribbon, using more hairs. White hair generally produces a smoother sound and black hair (used mainly for double bass bows) is coarser, producing a rougher sound. Lower quality (inexpensive) bows often use nylon or synthetic hair. Rosin, a hard, sticky substance made from resin (sometimes mixed with wax), is regularly applied to the bow hair to increase friction. In making a bow, the greater part of the woodworking is done on a straight stick. According to James McKean, "the bow maker graduates the stick in precise gradations so that it is evenly flexible throughout." These gradations were calculated by François Tourte, discussed below. In order to shape the curve or "camber" of the bow stick, the maker carefully heats the stick in an alcohol flame, a few inches at a time, bending the heated stick gradually to the proper shape. A metal or wooden template is often used to get the exact model's curve and shape while heating.

Up until the standardization of the bow by François Tourte c1785, most bows with rare exceptions remained anonymous (before 1750). And although François Tourte attained an enormous measure of fame in his own lifetime, the tradition of the anonymous bow maker was still so strong that theorists like Woldemar and Fetis called Tourte's new-model bow not the Tourte bow but the Viotti bow, after his contemporary the violinist.- David Boyden (After his father's death, Tourte, in collaboration with the violin virtuoso G. B. Viotti, made important changes in the form of the bow in the Classical period between 1785 and 1790. They lengthened them slightly, to 74 – 75 centimetres, and used more wood in the tip and a heavier nut.)
