That was an awesome performance and the instrument is beautiful looking and sounding.

Each is connected to the keyboard, complete with smaller black keys for sharp and flat notes. But unlike a piano, it has no hammered dulcimers. Instead, there are four spinning wheels wrapped in horse-tail hair, like violin bows. To turn them, Zubrzycki pumps a pedal below the keyboard connected to a crankshaft. As he tinkles the keys, they press the strings down onto the wheels, emitting rich, sonorous tones reminiscent of a cello, an organ and even an accordion.
