Some violinists, like Leonidas Kavakos, use bow vibrato by moving the right hand up and down slightly to change the angle and pressure of the bow and thus oscillate the pitch and intensity of a note. The first known description of this technique on violin was by Francesco Geminiani. This technique was not limited to violin but was known to players of all string instruments in Italy, France, Germany, and England during the Baroque era. Sylvestro Ganassi dal Fontego is known to have described this technique for the viol da gamba as early as the 16th century.
