 SCP-381 comprises seven unbound pages of yellowing paper sheet music. Each page contains eight bars of a contrapuntal polyphonic baroque choral composition. Anyone who touches SCP-381 abruptly begins to sing from the beginning of the composition in a range suited to their age and gender, but with professional level competence. When the singers reach measure, all non-Roman Catholic Christians in the area, including the singer if applicable, will spontaneously burst into flame that extinguishes only upon cessation of life function and cannot be extinguished by any available means. The flame is otherwise normal, emitting heat and light as would be expected.
