Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be held within a secure facility sized approximately by 7m x 7m x 7m. SCP-XXXX is not to be within 1 meter of contact with any human Personnel. Testing that involves any human subject is to be approved by over two Level 3 Personnel. Testing that does not involve a human subject should be approved by only one Level 3 Personnel.
Description: In appearance, SCP-XXXX is a Casio PT-80 Electronic Keyboard, presumably manufactured in the 1980's. The keyboard was discovered in a small two story house in the town of Chester located in the United Kingdom. Screaming was heard by surrounding neighbours who informed the police force of the noises coming from the house. On discovery, the police force discovered a presumable corpse playing "Für Elise" on SCP-XXXX. Once removed from the chair of which the corpse was sat upon, the corpse prominently melted into a form of black mucus. The corpse of those who play SCP-XXXX has been classified as SCP-XXXX-1.
Addendum XXXX.1: Effects on the Human Body ██/█/██ After several tests on SCP-XXXX including D-Class Personnel, it has been discovered that SCP-XXXX has the ability to melt ones brain into the dark, tar-like mucus that made up the corpse on discovery. Upon contact with any key, the now disclosed SCP-XXXX-1 has been noted to "not be able to stop playing" as they continue to repeat Für Elise over and over again. The Human subject repeatedly screams until eventually they are completely encased in the tar-like mucus. Although their screams are silenced, however, they continue to play Für Elise until forcefully removed from SCP-XXXX.
Addendum XXXX.2: Communication ██/██/██ SCP-XXXX has shown signs of communication over the coming months. At this current time, SCP-XXXX has only the ability to talk through the notes it can play, these being: A, B, C, D, E, F, G. This method of communication was discovered when [DATA EXPUNGED] was closely examining the abnormal electronics that make up that of SCP-XXXX. After discovery of this ability to communicate, an interview regarding Dr. James Afton and SCP-XXXX was organised in order to more closely understand SCP-XXXX's intentions and thoughts after its now gained sentience. The following is the interview conducted by Dr. James Afton during the investigation of SCP-5328's current signs of sentience.
