Jew's harps of Belarusian master Pyatochenko can considerably differ in the timbre of sounding and tongue hardness.
The length of a middle-sized tongue is 80 mm. The instrument has a minimal gap, hardness of a steel body is medium (can be soft). While playing it is better not to press the body, and the precision of beat should be as high as possible. It is good to play these jew's harps in slow or medium pace, but if you feel the dynamics of the tongue i, you can play more intensively.
The combination if mechanic paramenters of a tongue and sound timbre allow to use rythmical breathing to the maximum. As a result, we have a distinct and good perceptible sound. The sounding of the jew's harp is symmetrical in both sides. It is suitable for begginers and for those who continue. It comes with opened wooden cover.
