Occupying a place in size and sound height between the Pacific and the Little, Triangular Aman-Huur has the same typical set of qualities presented to Mongolian jaw harps - a sound replete with mechanical sounds and good handling. In this case, the ratio of pitch, length and stiffness of the reed provides a fairly comfortable, soft playing.
