khomus with large gaps, a quiet and deaf sound with proper holding. But the picture changes, if you grab the instrument in a heroic way, pinch it in a fist so that the frame arms will converge - the gaps are even and a full voice will appear. Although the full spectrum and the sensitivity that the jaw harps, "compressed" by the master in the manufacture, still cannot be achieved. And it will not get rid of extraneous sounds, but they can be made imperceptible, inflicting very strong strokes on yourself - the maximum volume of Sedalishchev's khomus at a decent timbre level is quite colorful and saturated. To touch the reed frame with such a design and is quite difficult. That's just the dynamics disappears - all the sounds will be loud.
