приструнок) is a term used for the additional unfretted strings strung across the body of Ukrainian folk instruments such as the kobza, bandura, and torban.
These additional strings are thought to have appeared on these instruments as early as the 17th century.
feel that these additional strings appeared later in the mid to late 18th century.
Due to the neck (and some modern and traditional designs even have a neck with frets, such as the kobza of Pavlo Konoplenko-Zaporozhets), which allowed the game to be played in several keys, a few strings were not necessary in principle to reproduce the melody.
In bandura, the playing of both basses and strings is conducted in a harp-like manner.
