The frame is cast iron. The key action is hoppered. Both keyboards have a common hammer mechanism. The keyboard of P. von Janko’s system (1856–1919) is 6-lined stepped (ladder-like). The piano is equipped with the “harmoniopiano” invented by V. I. Glavach (1849–1911), which is a pneumatic mechanism for acquiring tremolo. There are 3 pedals; the 3rd pedal is designed to control the mechanism providing tremolo sound. The upper front side is decorated with plated carving (a profile of R. Wagner) and 2 bronze candlesticks.
