Jews harp with a special adjustment of the tongue to obtain the effect of humming on inspiration (after stroke). In most cases, “buzzing” is achieved by a tongue bent from the plane of the frame, which leads to asymmetry of its movement and pronounced stratification of sound. It is popular among beginners who do not notice the loss of general musical balance - a more subtle but important matter. In the Shablish, the negative component is minimized. And, although this is still the same classic Ural vargan with a supersaturated, bright and loud sound, its ability to hum does not affect the timbre. The best option for those who really want, or just not needed all sorts of overtone conservatories.
