| 2: Installation of a music barrel | |||||||||||||||||||||||||||||

|
The "Mechanical Orchestra" organ has interchangeable barrels that are inserted through a special opening in the carcass of the musical mechanism. Due to the size of the barrels, it takes two people to insert them. They were produced of wood and covered with paper on which markings were made. Then metal pegs (nails) and staples of varying length were inserted into the surface of the barrel following the markings. The length of a staple was proportional to the length of sound produced and their relative positions on the barrel determined which piece of music would be played. Twelve barrels recording different pieces of music have survived. As the mechanism operates the barrel not only rotates but also slides along its axis of rotation. Each barrel carries a broad band of pegs and staples driven into its surface. The length of the barrel determines the time the music will play for. The fact that the barrel moves along its axis means that longer pieces of music can be played. | ||||||||||||||||||||||||||||
