Dutch piano restorer Frank Bernouw has painstakingly restored a stunning Hupfeld Phonoliszt-Violina, a self-playing, multi-violin orchestrion that plays a variety of concertos quite beautifully, if not a bit mechanically. This unusual instrument was invented in 1907 by Ludwig Hupfeld AG and “dubbed the “8th wonder of the world”, per Antique HQ.
Three violins (each with only one active string) mounted vertically were played by a round rotating bow made of 1300 threads of horse hair, according to the program on the roll of perforated paper. The small bellows replaced the violin player’s fingers, pressing on the strings to obtain the necessary notes. The piano can be driven either unaccompanied or together with the violins. It controls 38 accompaniment keys with 12 high notes (one octave) in extension. The whole pneumatic systems are controlled by an electric engine of uninterrupted current.
