Deletion of Clustering of composers

Comment: With all due respect, V. hasn't shown anything of the sort. It could easily be POV or even spam, we don't know, and it certainly runs the risk of being thought  or otherwise unbalanced, as the article gives precisely no weight to anyone else's published material. Further, it doesn't cite "multiple, independent sources", but essentially one dependent source, namely himself

Comment: this odd   fragment is written by a user with the same name as one of the authors of each of the two papers cited, so it appears we have a  here, with the suspicion this is a promotion. The same user (in one of his other 3 edits) added a cite to another of his papers on the same topic to Geographical cluster. No independent sources found

Comment: The material may not be enough for a stand-alone article, but it is certainly worthy of inclusion in Composer. This is most definitely not |original research or an "essay". It has been published in a peer-reviewed journals and although the exact phrase may not occur frequently, the concept/phenomenon has been studied and noted by others as well.

The COI argument has no bearing whatsoever on whether reliably sourced and useful, encyclopedic information should be incorporated into Wikipedia

Comment: As Voceditenore has shown, it's not  but part of the scientific discourse. Wikipedia has many articles where academic authors have contributed and cited their own papers. This is generally a good thing

Comment: to Composer. There is some reliable sourcing for this, and it is cited in peer-reviewed academic journals, but in my view the coverage to be found is not significant enough to warrant a separate article under . Hence merge is the appropriate course
