The frame is held firmly against the performer's parted teeth or lips (depending on the type), using the jaw and mouth as a resonator, greatly increasing the volume of the instrument. The teeth must be parted sufficiently for the reed to vibrate freely, and the fleshy parts of the mouth should not come into contact with the reed to prevent damping of the vibrations and possible pain. The note or tone thus produced is constant in pitch, though by changing the shape of the mouth, and the amount of air contained in it (and in some traditions closing the glottis), the performer can cause different overtones to sound and thus create melodies.
According to the Encyclopædia Britannica Eleventh Edition, "The vibrations of the steel tongue produce a compound sound composed of a fundamental and its harmonics. By using the cavity of the mouth as a resonator, each harmonic in succession can be isolated and reinforced, giving the instrument the compass shown."

“By using the cavity of the mouth as a resonator, each harmonic in succession can be isolated and reinforced, giving the instrument the compass shown. The lower harmonics of the series cannot be obtained, owing to the limited capacity of the resonating cavity. The black notes on the stave show the scale which may be produced by using two harps, one tuned a fourth above the other.”
The earliest depiction of somebody playing what seems to be a Jew's harp is a Chinese drawing from the 3rd Century BC, and curved bones discovered in the Shimao fortifications in Shaanxi, China are believed to be the earliest evidence of the instrument, dating back to before 1800 B.C.E.[4][5] Archaeological finds of surviving examples in Europe have been claimed to be almost as old, but those dates have been challenged both on the grounds of excavation techniques, and the lack of contemporary writing or pictures mentioning the instrument.[6]
Although this instrument is used by lackeys and people of the lower class, this does not mean it is not worthy of consideration by better minds ... The trump is grasped while its extremity is placed between the teeth in order to play it and make it sound ... Now one may strike the tongue with the index finger in two ways, i.e., by lifting it or lowering it: but it is easier to strike it by raising it, which is why the extremity, C, is slightly curved, so that the finger is not injured ... Many people play this instrument. When the tongue is made to vibrate, a buzzing is heard which imitates that of bees, wasps, and flies ... [if one uses] several Jew's harps of various sizes, a curious harmony is produced.

Etymology
There are many theories for the origin of the name Jew's harp. According to the Oxford English Dictionary, this name appears earliest in Walter Raleigh's Discouerie Guiana in 1596, spelled "Iewes Harp". The "jaw" variant is attested at least as early as 1774[8] and 1809,[9] the "juice" variant appeared only in the late 19th and 20th centuries.
It has also been suggested that the name derives from the French "Jeu-trompe" meaning "toy-trumpet".[10] (Though in the French idiom, if two substantives are joined together, the qualifying noun is invariably the last.)[11]
Both theories—that the name is a corruption of "jaws" or "jeu"—are described by the OED as "baseless and inept". The OED says that, "More or less satisfactory reasons may be conjectured: e.g. that the instrument was actually made, sold, or imported to England by Jews, or purported to be so; or that it was attributed to Jewish people, suggesting the trumps and harps mentioned in the Bible, and hence considered a good commercial name."[12]
