Bandura technology and development With the growing appreciation of bandurist capellas as an art form came the accelerated development of technology related to the performance on the bandura. At the beginning of the 20th century the instrument was thought to have gone into total disuse. At that time it had some 20 strings with wooden pegs (4 basses and 16 prystrunky). The volume obtained from the instrument was not loud enough for the concert stage. In 1931 the first mechanisms were developed, which allowed the bandurist to quickly retune his instrument in a variety of more distinct keys.
