Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be stored in a controlled environment. Humidity levels should never fall below 25% and never exceed 45%. The temperature should never fall below 25° C and never exceeding 30° C. SCP-XXXX should always be handled using nitrile or vinyl gloves to prevent staining the paper.
SCP-XXXX should be handled with care when being transported, and not to be played more than once a week to prevent excessive wear. The paper has ripped in several places and has been taped back together with clear masking tape, this is an acceptable way to repair to repair SCP-XXXX in case of tears. This method may not be viable if a tear is too close to the perforations, in such cases Dr █████ should be consulted on a plan of action.
Notice from site-██ ethics committee: SCP-XXXX is not to be played for longer than 5-minutes, destroying a person's vocal chords is inhumane and not allowed anymore
Description: SCP-XXXX appears to be an old piano roll, a significant amount of weather damage is visible, and some parts of the paper are torn in places likely from wear from normal use combined with the effects of aging. SCP-XXXX consists of a paper 28.58 cm in width and 5.4 m in length. The paper lacks some control codes usually present in piano rolls that conform to the 1908 Buffalo convention, so some things such as note velocity are unknown.
When SCP-XXXX is played on a replaying piano anyone [within 1m of the piano/that hears the piano/the immediately closest person] will begin to have their voice "tuned" to the frequency of the note currently being played by the replaying piano. The "tuning" effect is similar to what results from auto-tuning software, where the voice of the person gets pitch corrected to the desired frequency corresponding to a note played, usually on a midi score. SCP-XXXX does this via manipulation of the person's vocal chords, and because of the nature of the piece, causes harm to the vocal chords. The anomalous effects of SCP-XXXX are only noticeable after 2-3 minutes of it playing, injury can occur after 4-7 minutes, and permanent damage occurs at 8-10 minutes. As SCP-XXXX contains very extreme high and low notes, and many chords spanning the entire 88 note scale it puts an intense strain on who ever is affected by it, and especially dangerous for people with badly developed vocal muscles.
The music piece stored on SCP-XXXX is similar to Alfredo Casella's "trois pièces pour pianola" and Igor Stravinsky's "The Rite of Spring", although with little to no melodic progression. The piece seems to have been composed solely for the purpose of harming the "singer" and not for performance.
SCP-XXXX was found in the abandoned mining town of ██████, New Mexico when the foundation was alerted by local law enforcement agencies, when an explorer for the YouTube channel "█████████" was admitted to the ████ ██ ██████ hospital with unusual symptoms. After the victim had recovered he was questioned and a mobile task force was dispatched to the location of SCP-XXXX as described by him. Along with SCP-XXXX a diary possibly decribing the origin of SCP-XXXXX (see addendum 1 for relavent entries) was discovered. SCP-XXXX was moved to site-██ and the diary
Addendum: These pages have been transcribed and attached to this document because of their percieved relevance to SCP-XXXX. The rest of the pages from the recovered diary can be found in dry storage unit U-5TC at site-██.
