The modified "Black" jaw harp Glazyrin combines the sonority of the popular original version and the convenience of alternating strokes, which was so lacking in instruments with a long and soft reed trigger. The new design is much better suited for alternating strokes, the most noticeable is the significantly reduced backlashes. The timbre of the sound is just as thick and saturated (even too much for academic overtone play) - but for an ordinary timbre-rhythmic, it fits perfectly.
