Item #: 4761
Object Class: Safe
Special Containment Procedures: SCP-4761 must be contained in soundproof box 3 meters wide, 4 meters tall and 3 meters long. Around the box should be a 50cm thick shell of metal. The piano and box should be cleaned every 5 days and inspected every 2 days incase of damage. Cleaners of the cell should be in a suit made of ██████ to not be attracted to the piano.
Description: SCP-4761 is an old broken piano from the 19th century found in a barn in █████. Although all strings are missing, all 88 keys still work. Any human in a 3 meter (approximately 9 feet, 10 inch) radius will get the urge to play a song (which is different for everyone) before blacking out. Anyone who hears the notes would immediately fall into REM sleep.
After blacking out, the victim will have visual hallucinations of SCP-4761-1, a black humanoid creature with a cow skull on its head with the approximate height of 4761-1 being 2m 85cm. SCP-4761-1 lurks in the corners in the victim's eye, ready to attack. But, if the victim of SCP-4761 turns to the direction, 4761-1 will move positions. If the victim gets caught by 4761-1, it will be sent to a location known as 4761-2.
4761-2 is a never ending hallway where faint piano sounds can be heard. All Class D victims went insane in the first 1 hour of 4761-2, except one. Class D named ██████ ███████ exited by finding a piano and playing the same song SCP-4761 urged him to play at the start.
Honestly to say, i don't know. There was no harmony, no chord pattern, just notes that get trapped in your mind. -The Escapee of 4761
