This Helicoidal Orchestra music box is truly a one of a kind due to its ability to play long overtures, operatic airs, and other musical compositions without interruption.
This Helicoidal Orchestra music box was produced by the Swiss company Paillard in 1890.
The Paillard family was responsible for several important developments in cylinder box design and manufacturing, including improvements to tune changing, interchangeable cylinders, and the revolver box.sources
This helicoidal music box features one cylinder with all pins arranged on a continuous spiral.
The need for shifting from one cylinder to another to another has been eliminated here as the cylinder is screw-fed and slowly and continuously moves to the side in synchronization with the pins. Such an arrangement proved to be ideal for playing long overtures.sources
