badulka

thumb|A street musician in Toulouse, France, playing a gadulka. The gadulka () is a traditional Bulgarian bowed string instrument. Alternate spellings are "gǎdulka", "gudulka" and "g'dulka". Its name comes from a root meaning "to make noise, hum or buzz". The gadulka is an integral part of Bulgarian traditional instrumental ensembles, commonly played in the context of dance music.

The gadulka commonly has three (occasionally four or five Mincho Minchev) main strings with up to sixteen sympathetic resonating strings underneath introduced by the legendary Mincho Nedyalkov. Only the main melodic strings are touched by the player's fingers and the strings are never pressed all the way down to touch the neck. The gadulka is held vertically, with the bow held perpendicular in an under-hand hold.
