jaw harp with medium-sized gaps - the width of the spectrum already comes out of the region of "deafness", but does not yet come to the area of sharp sound; sensitivity is not bad, the mechanics are good. In many instances, the reed is bent from the plane of the frame, which makes the timbre uneven, stratified, and makes it possible to "buzz" with one breath. The instrument at the level of cast Vietnamese jaw harps is low, by modern standards.
