Description: SCP-XXXX is a large book of musical scores. The exact date of its creation is unknown, but the musical notation is typical for the late 1700s-early 1800s. On its own, it has no anomalous properties. Listening to the music of SCP-XXXX allows the user to perceive a different reality. For an unknown reason, the person playing the music does not experience any anomalous effects.
The listener does not experience any anomalous effects during the first minute of music. After the first minute, their sense of hearing begins to disappear. Their other senses begin to distort as well, as they perceive a second reality overlapping with their normal one. The listener can interact with anything they find in the second world, and some reports describe the listener getting stuck on invisible walls.
