scp-407
Description: SCP-407 is a song in an unidentified language, seemingly sung a cappella. The voices are thought to be human. The tape containing SCP-407 was found with one track of approximately thirty (30) minutes duration, though the abrupt ending suggests there may be more. The song has been described by all listeners as something along the lines of 'soothing', 'glorious', and 'beautiful'.
While SCP-407 is played, rapid cell generation seems to occur within auditory radius. This effect seems to occur at the cellular level, and does not require the subject to be able to hear the music. The changes seem to only affect multi-cellular organisms at first, but quickly begins to affect mitosis in single-celled organisms.
