Flute (frula) is the most typical and the most widespread wind instrument in the music practice of Serbia. Although it has been popularly called frula in recent times, this instrument is known under the older names as svirala (svirojka) and sviralče (svirajče) – depending on the size of the instrument – larger or smaller – in the practice of the western and central areas of Serbia, and as duduk and duduče – in the tradition of the eastern and southern regions of Serbia. The upper end of the flute is precisely cut and partially closed with a stopper, below which a square opening with a sharp edge is incised on the back. It has six playing holes on it; in recent times, on smaller instruments, a seventh hole has been added on the back. The widespread use and the great popularity of flute playing in Serbia has contributed not only to the mastery of performing skills, but also to a wide range of uses – as a shepherd instrument, as well as a part of folk celebrations and gatherings, accompanied with singing and dancing. Flute playing is supported by instrument builders, individuals or specialized workshops, who preserve the craft of flute making.
Flute playing, as a sphere of oral traditions and expressions, i.e. performing arts, is present among the population throughout the territory of Serbia.
