Piano rolls were a medium for recording and reproducing music on player pianos, originating in the late 19th century. These rolls consist of a long strip of paper with holes punched in a specific pattern to indicate which keys should be played and for how long. Each roll corresponds to a particular piece of music, allowing the player piano to perform the composition automatically when the roll is fed through the instrument. This technology offered a way to share and enjoy music in homes, contributing to the popularization of various genres before the advent of digital recordings. Today, while player pianos have seen a decline in mainstream popularity, piano rolls are still valued by collectors and enthusiasts for their historical significance and the unique sound they can produce. Plus, we haven't even touched on the decor aspects yet. You can add transfers or paint a design on each roll and hang it with just enough of the corresponding holes being shown. Or leave them open in their boxes and display in a vignette of rolled up music sheets.
