The master made a minimum of effort to create this model of jaw harp: a simple shankobyz is a bent piece of untreated round steel rod with unevenly trimmed frame arms and a very thin reed with a large gap. A rare case where the sound of jaw harp corresponds to its appearance: quiet and faded. The dynamic range is very small; strong breathing causes more whistles of air than changes in sound; soft reed is easy to touch frame arms, although not as much as in Hungarian dorombuses. But it is still possible to play this instrument, within the limits of the opportunities provided by it, especially slowly, on overtones. Quickly - a thin reed can't cope.
