No small khomus with strong mechanical vibration. The sound is far from the brightest, but due to articulation, changes in the volume of the oral cavity, it varies within fairly wide limits. The main features are smoothness (the absence of high frequencies due to large gaps) and the monolithic nature of the extracted sounds. You can play both at low and high speeds; in the latter case, the jews harp is very stable; but because of the great rigidity, it takes a lot of effort to "accelerate" it, yet the return will not be proportional to the costs anyway.
