Barrel for a mechanical organ c. 1815 - 1825

Harmanus Dolman's "Barrel for a mechanical organ" (c. 1815-1825) is a set of three wooden cylinders, each covered in intricate patterns of punched holes. These holes, acting as a form of early musical notation, would have been used to play music on a mechanical organ. The barrels, standing in a row, demonstrate the ingenuity of 19th-century musical technology and provide a glimpse into the craftsmanship of the time. Their design showcases the precision required to create these intricate instruments.
