The egg is long and three and a half stories high, weighing in at . It is the second largest pysanka in the world. The biggest one was built in Kolomyia, Ukraine in 2000.
Dvoyanka
The Bulgarian dvoyanka is a double flute made of a single piece of wood, with six sound holes on one side. It is most frequently made of ash-wood, plum tree, pear tree, cornel or boxwood. The tune is played on the right pipe, while the left pipe provides a flat tone (or drone) as accompaniment. The playing structure on the right pipe is similar to that of the music played on the kaval. The dvoyanka has traditionally been an instrument favored by shepherds. Line-dances and lively melodies are frequently played on it. It is a known fact that shepherds directed their flocks by their playing, since sheep remember and recognize a melody in time. A shepherd could "teach" his flock to start from the pen towards the pasture at one melody, and to return to the village in the evening at another. The instrument bears similitudes to the dvojnica, an instrument typical for the regions of Central and Western Serbia and Serbian regions across the river Drina, which is made and played somewhat differently.
The dvoyanka is a double pipe (gaida), which has a form of a rectangular prism or which is more rarely is composed form two parallel cylindrical tubes. It has a length from 30 to 40 cm. All of the two tubes begin with a bill formed nozzle in which the tone is produced with an ordinary blowing. When playing on a duduk the two tubes are temporarily blown.
