A bandura (Ukrainian: бандура) is a Ukrainian plucked-string folk-instrument. It combines elements of the zither and lute and, up until the 1940s, was also often called a kobza. Early instruments (c. 1700) had 5 to 12 strings and resembled lutes. In the 20th century, the number of strings increased initially to 31 strings (1926), then to 56 strings – 68 strings on modern "concert" instruments (1954).
