Abstract
The history of bow makers records various changes in the construction of the bows, in close conection with the expansion of the artistic repertoire and the development of the instrumental technique of the bow and strings instruments. The eightheenth century brought an important concern for these changes, but only in the late of the 1700s there will be a standardization in the lenght and shape of the bows. After a period of transition, full of multiple attempts, Francois Tourte is the one who creates the model we call today the modern bow.
