Object Class: Safe
Special Containment Procedures: SCP-5869 should not be attempted to be contained in anyway. Instead SCP-5869 should be allowed to wander the halls of the facility it is being held in. SCP-5869 should be politely asked to stay in a facility, when asked it will do so until told otherwise.
Description: SCP-5869 appears to be a caucasian male in his early to mid thirties. Alongside SCP-5869 is a musical instrument, dedicated SCP-5869-1.
Instances of SCP-5869-1 vary in the instrument and material. Instruments include but are not limited to; Trombones, Trumpets, Bases, Clarinets, and manly other musical instruments. The material for said instruments vary and can often be made out of unconventional materials, such as bone or rock. See Addendum for a list of instruments and materials manifested.
When SCP-5869 enters a room, ambient music will be heard, regardless of devices or instruments present. The music will be big band jazz, however SCP-5869 can take requests for any song or genre imaginable. Any attempts to contain SCP-5869 have failed, no matter what measures are taken SCP-5869 will escape his contain cell and wonder the facility halls. Staff who interact with SCP-5869 often report a feeling of contentment and joy, often comparing the entity to one “Mr. Rogers”.
SCP-5869 will not harm any personal or entity it comes across unless said personal or entity harms or damages instances of SCP-5869-1. If a situation like this occurs, every noise within a 5km distance of SCP-5869 will go totally silence, and in an instant, the entity who harmed SCP-5869-1 will proceed to have their eardrums burst and shortly after their organs as well. SCP-5869 will then stop playing music for a period of 6 hours. There has so far been no way to damage SCP-5869, and despite looking fairly young, it is believed to be at least ████████ years old.

Closing Statement: SCP-5869 was asked to play at the wedding of two foundation staff. Not only did SCP-5869 agree to go, and seemed extremely excited, but it manifested an instrument currently of unknown origin. It operates as both a wind and string instrument and was described as having a sound similar to that of a harp. It disappeared after the wedding, and SCP-5869 has yet to remanifest it for future study. The instrument currently goes under the name ████████.
