A jew’s-harp is a musical instrument consisting of a simple frame with a vibrating central prong; it’s held against the teeth to play, using the mouth as a resonating cavity. It was also known as a “jew’s-trump” in period, and a “mouth harp” in modern times. The jew’s-harp is a period charge, found in the arms of Brenntl, 1548 [Vigil Raber’s Armorial of the Arlberg Brotherhood of St. Christopher, fo.120]; the instrument itself is illustrated in Virdung’s Musica Getutscht, 1511 [Montagu 91]. The jew’s-harp has its prong to chief by Society default.
