== Klang (Stockhausen) review == 
 Many thanks, Finetooth, for the many helpful suggestions in your review, most of which have now been implemented. I have responded to your seven open questions on the review page, but I would like to ask your advice about one point you raised. You stated, "'Himmelfahrt (Ascension), for organ or synthesizer, soprano, and tenor. 2004–05 (36 mins.). Work number 81. The specified colour is deep violet-blue.' - Although the article seems well-sourced, it's good practice to provide at least one source for every paragraph except, usually, the paragraphs in the lead. Most paragraphs in the article are sourced, but this one isn't". I concede I have been concerned about this. It is not usual in music articles to supply an inline citation to the score of a composition that is the subject of an article or section, at least as far as things like the title of the work, opus number, instrumentation, etc. are concerned. The associated colour, however, is unusual, and so may require a citation (also for the other 20 Hours—or even 23 Hours, since the colours were assigned for the three planned compositions that were never written). However, in the case of the First Hour, this entails citing the cover of the score or the colour wheel published by the composer in at least two different places. Unlike most of the other scores, those for the first four Hours do not include a statement of the standard HKS number in the preface—it is necessary to look at the type on the cover (or consult the colour wheel, which cannot be reproduced anywhere near as accurately as a single HKS colour). Do you think this is a reasonable way to cite a colour, or does this require "expert knowledge" to interpret, in the same way that a traditional musical score with a three-sharp signature requires expert knowledge to determine whether it is in A major or F minor? If you think this may be a problem, do you have any alternative suggestion?—
