- Vergilij Atanassov
Double duct flute of Bulgaria; found most often in west and southwest Bulgaria and those parts of the Rhodope mountains where two-part singing is predominant. The dvoyanka usually consists of two parallel cylindrical pipes bored in one rectangular piece of wood such as oak or ash, 29 to 50 cm long. It can also be made of two separate cane pipes glued or tied together with a cord. In the southwest Rhodopes, the dvoyanka is made of pine with the pipes glued or joined together with a wooden clamp. The melody pipe has six fingerholes, producing a major diatonic scale. The parallel drone pipe has a single hole in the side, level with the first fingerhole of the melody pipe, and sounds in unison with the second degree of the scale. The dvoyanka produces a soft sound and is used to perform slow melodies.
