The Dan Moi is the traditional 'Jew's Harp' (or jaw's harp, or trump, or guimbarde) of the Vietnamese mountain people Hmong. Hand-made by a small number of excellent local craftsmen, this brass instrument captivates even novices by being easily playable and having a brilliant sound, rich in overtones. Playing the Dan Moi is effortless and enjoyable. ✅ In contrast to other types of trumps, the Dan Moi must not be pressed against ones teeth to produce its full and warm sound. Rather, the instrument is gently rested against the player's lips with one hand while the other plucks the tip of the reed softly. Moreover, the Dan Moi affords players with an almost unlimited range of possibilities for the creation of sound effects since mouth and tongue are given considerably more freedom than with other types of trumps.
