Frame zither

Jacqke/Frame zither
	Liberian zither with calabash resonator. Called a "harp" by its collector; however, on a harp the "plane of the strings lies perpendicular to the resonator's surface." The strings running parallel to the gourd resonator make this a frame zither under Hornbostel-Sachs.

Stylized drawing in a medieval manuscript shows a man playing an instrument with strings stretched across a frame. Text reveals it is a psaltery, which means it would have a board behind the strings and not be a frame zither.

Frame zither is a class of musical instrument (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 made from a frame.^[1]

Frame zithers are musical instruments in which strings are strung across an open frame.^[2] They could be similar to harps and psalteries which can also have strings stretched across frames. However, in harps the strings run from the frame to a resonating table embedded into the frame on the frame's other end. Psalteries may also have a frame, but behind the strings (parallel to them) is a board, the top of a box which acts as a resonator.

Musicians may add a resonator as is done with a bow harp; they can attach or put the instrument into a calabash gourd or a ceramic pot.^[3]

Under the Hornbostel-Sachs system of musical instrument classification, any frame with strings stretched across, and without a built in resonator, would count as a frame zither. In musical instrument encyclopedias, however, there are few or no examples of frame zithers except those found in Africa. Potential examples include medieval European illustrations; these however are not clear and could equally illustrate forms of harps or psalteries.^[1]
