Deletion of Negative harmony

Comment: ping|Sandstein}} There is no policy compliant redirect target. No reliable source mentions ''Negative harmony'' in the context of Jacob Collier. He writes about it online and there are a lot of blog posts about it but no RS and nothing in his article that discusses the term. If the term is not mentioned in the article then it is not a valid redirect target and without a RS it can not be mentioned in the article. {{pb}} Ernst Levy is not a valid redirect either. Collier claims Levy discussed it in ''Musical Theory'' but Levy never uses the term in the book – at least a search of the PDF I have of it does not find it. Maybe Levy discusses the ''concept'' which Collier used to derive the term but he does not coin ''Negative harmony'' as a term. {{pb}} There are simply no reliable sources ''at all'' which discuss ''Negative harmony'' in general or as the particular note progression described by Collier. Someday it may get attention in the music theory literature but as of now, to the best of my knowledge looking for information both for this AfD and for when I PRODed the first version, there is nothing. {{pb}} Without ''any'' RS deletion is not even a judgment call. The article fails  and as a neologism fails  before we even get to a discussion of notability. There are literally ''no'' policy compliant arguments for inclusion of this subject

Comment: Since the term is the creation of a YouTube artist and the source he quotes does not reference the term; the article can be deleted under #6 ({{tq|"Articles that cannot possibly be attributed to reliable sources, including neologisms, original theories and conclusions …"}}) and/or #7 ({{tq|"Articles for which thorough attempts to find reliable sources to verify them have failed"}}). I do not see the point of further relisting
