The modified "Black" jaw harp Glazyrin combines the sonority of the original version, which is very popular, and the convenience of alternating strokes, which was so lacking in instruments with a long and soft reed trigger. The new design is great for fast alternating strokes - no punches are allowed, the finger does not cling to the ring and reverse swings are minimized. 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.
