A gdulka or gadoelka (Bulgarian: Гъдулка) is a Bulgarian knife fool. Three strings are used as a melody string; the remaining 10 are resonance strings and are voted in the scale (s). A gdulka thus has a kind of 'built-in' reverberation. The gdulka is usually used as a melody instrument in Bulgarian folk music.
Unlike a violin, the strings are not pressed to shorten the string (and thus get a higher tone), but the nails are pressed against the string.
The three melody strings A, E, a lie in the comb while the resonance strings b, c #, d, e, f #, g, g #, a, b, c # walk through holes in that comb. The comb rests on one side of the top sheet, on the other side on the backside by means of a wooden support, similar to a pile in a violin. The mood of the instrument will be played especially in crossed-to-peer types: D, A and E and the minor variants Bm, F # m and C # m plus some gypsy tunes.
The bar is a bit more primitive than with modern string instruments and is held by hand. Gdulkakam 3 play strings on top and 10 resonance strings through it Also see
