Similar instruments are found in
Albania (cyla-diare),
Macedonia (piska),
Greece (disavli),
Romania (fluierul gemanat), and
Serbia (dvojnice) in one build or another. One difference, however, is that where the Bulgarian dvoyanka is rectangular in shape, where the two tubes are bored straight through a single block of wood and the material in between remains intact, in Albania and Serbia the wood between the tubes may be cut away so that they resemble two separate "legs" (the instrument then resembles an upside-down Y; see other instruments in this case). ==See also==
