CorenSearchBot has mistakenly identified something in this newly created article as infringing copyright on a YouTube item including a video with music from a related composition, Pole. There is no text in this article that duplicates anything except the composer's name from that YouTube site, there are no video links in this article, and no duplication of any copyrighted images. It is possible that, somewhere on YouTube, material from the Wikipedia article Karlheinz Stockhausen is quoted. Several sentences from that Wikipedia article are duplicated here. It should also be noted that the music on YouTube is copyrighted, and its posting there is probably a breach of this copyright.—Jerome Kohl (talk) 07:28, 25 January 2012 (UTC)[reply]
Closer examination shows that the YouTube item, uploaded by peledoperro on Nov 5, 2011, quotes (in an initially hidden page) the entire Wikipedia article Pole (Stockhausen), which was created (by me) on 10 July 2011. The YouTube page correctly attributes the article to Wikipedia. Because Pole and Expo are closely related compositions (the scores are actually published together as a pair), naturally the new Expo article contains some of the same material as the older article on Pole. Since the duplicate material is entirely from the public-domain Wikipedia article, there is no question of copyright infringement.—Jerome Kohl (talk) 18:06, 25 January 2012 (UTC)[reply]
