Item #: SCP-5815
Object Class: Safe
Special Containment Procedures: SCP-5815 is to be kept in a standard guitar case and located within Site-77's Safe SCP wing. If SCP-5815 is being tested upon, it should be handled with fragility in mind. SCP-5815 should be easily accessible for SCP-5815-2.
Description: SCP-5815 is a 40" acoustic guitar, the guitar is made out of mahogany wood, the brand appears to be ██████.
SCP-5815 appears to be in a poor condition, with scratch marks on the back and a large chip on the side. Attempts to tune SCP-5815 have failed, as the position of the tuning knobs are unchangeable. Attempts to refurbish or restore SCP-5815 have also failed, as the strings cannot be cut by any string cutter. attempts to play SCP-5815 have resulted in failure, as SCP-5815 seemingly can't be played well by any personnel. SCP-5815 will sound off or incorrect when tested, not matter the skill of the player. SCP-5815 cannot be played SCP-5815 seems to only be able to be played well by SCP-5815-2.
SCP-5815-2 appears to be a tall humanoid figure, but remains invisible to the naked eye apart from a small outline. In 6 hour intervals, SCP-5815-2 will enter the storage facility of SCP-5815 and will begin to play it. SCP-5815-2 will continuously play the intro to ██████ by ██████ for the next 2 hours, before leaving the facility. If SCP-5815-2 is unable to reach SCP-5815 at the designated time, SCP-5815-2 will become very aggressive and will scream and shout, and become hostile to any personnel in the area. efforts to contain SCP-5815-2 during this phase have resulted in failure, as SCP-5815- cannot be touched, and can move through walls and floors, after the two hour time period is up, and SCP-5815-2 has been unable to come into contact with SCP-5815, SCP-5815-2 will leave the facility and return in the next 4 hours to try again.
SCP-5815-2 does not speak, and doesn't respond when being questioned. It will ignore any kind of contact made, and will continue playing SCP-5815.
Addendum 4430.1: Discovery
SCP-5815 was discovered in the back of a guitar shop in [REDACTED]. SCP-5815 was presumed to be broken until SCP-5815-2 entered the shop and started playing it. The employees of the shop attempted to stop SCP-5815-2 from entering the shop, but failed as SCP-5815-2 phase through them and continued on. The foundation was called in, and SCP-5815 was taken to site-77. SCP-5815-2 was not taken by the foundation but seemingly found his way to the facility anyway.
Addendum 5815.2: Observation Log
SCP-5815-2 is shown to be getting better at playing the piece every time he plays, and is shown to be nodding its head and tapping its foot. SCP-5815-2 has experimented playing its piece with power chords instead of normal playing, however it seems to prefer to play it with one note. Experienced site personnel have attempted to teach SCP-5815-2 but no successful experiments have been achieved.
On ██████, SCP-5815-2 returned to the facility to play SCP-5815 with a capo. Although this only changed the tone slightly of SCP-5815-2's playing, this raises questions as to where SCP-5815-2 goes between intervals of playing. Attempts to follow SCP-5815-2 have been unsuccessful.

Addendum 5815.3: Incident 5815-A
An experiment was carried out by on site staff to analyse SCP-5815-2's behaviour when SCP-5815 cannot be reached. SCP-5815 was placed into a locked steel containment chamber. 3 personnel from Mobile Task Force ████████████ stood armed outside the containment chamber. at exactly ██████, SCP-5815-2 entered a hostile state and used force to reach SCP-5815. All 3 personnel were killed during this enraged state being unable to damage SCP-5815-2 with heavy artillery. SCP-5815-2 reached SCP-5815 and returned to it's docile state and played SCP-5815 for the next 2 hours before leaving. No change in SCP-5815-2's behaviour was documented after this.
