In the system, bar zithers are made up of musical bows and stick zithers.[1] Musical bows have flexible ends, stick zithers are rigid or have only one flexed end.[1] Bar zithers, whether musical bow or stick zithers, often have some form of resonator. Examples of resonators include the player's mouth, an attached gourd or an inflated balloon or bladder.
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.[1]
