Violin construction and mechanics four open strings, usually tuned to G, D, A, and E. The strings run from a tailpiece attached to the base, across a wooden bridge, continue towards the neck of the instrument running parallel to the fingerboard, and connect to the pegbox located at the very top of the violin. They are wound around four tuning pegs that are mounted sideways through holes in the pegbox. The bridge helps to hold the strings in place, while the pegs maintain the tension necessary to produce vibration. Strings were first made of sheep's intestines (called "catgut"), stretched, dried and twisted. Contrary to
Trembita Musical Instrument Factory 19 instruments were made. These instruments were diatonically tuned with 34 strings, however they did not have sufficient volume and did not allow the player to play in different keys easily. Continual serial manufacture of banduras was set up in 1964. Vasyl Herasymenko developed an acceptable model instrument and also developed a serial process for the mass production of banduras. From 1964-68 some 300 experimental instruments were produced. These instruments became known as the "Lviviankas" . The first models had 58 strings which included 17 bass strings. This particular instrument differed from counterparts made at the Chernihiv Musical Instruments Factory
