Munniharppy are not distinguished by external brilliance and severity of forms; they are single piece instruments, whose authenticity is even more emphasized by unusual cases of birch bark. The nature of the sound corresponds to the image - this is, first and foremost, the embodiment of the old traditions of making a frame, without the use of modern tools. The tongue and, consequently, the acoustic properties has got a minimal attention - just to make a sound. Jews harps are quiet, deaf - for collectors of ethnic rarities.
