SCP-066 is an amorphous mass of braided yarn and ribbon weighing approximately one kilogram. Strands of SCP-066 may be taken individually and manipulated; when this is done, a note on the diatonic scale (C-D-E-F-G-A-B) is produced by the object. When a set of six or more notes are produced, SCP-066 will produce a benign effect of varying nature and duration. SCP-066 will not respond to manipulation while any effect produced by it is in progress. (copied from wiki)
