Bar zither

Bar zither is class of musical instruments (subset of zither) within the Hornbostel-Sachs classification system for a type of simple chordophone (stringed instrument), in which the body of the instrument is shaped like a bar.

[1] Musical bows have flexible ends, stick zithers are rigid or have only one flexed end.

Examples of resonators include the player's mouth, an attached gourd or an inflated balloon or bladder.

According to Sachs,[2] A stick-zither has a stick in place of a resonating body and always needs an additional resonator, generally a gourd, sometimes the mouth of the player.Instruments may be monochords (single stringed) or polychord (multiple stinged).

[1] They may also be idiochords (string made from the bar or stick) or heterchords (string made of separate substance from the bar or stick.
