Diatonic interval? 
As the article stands, a reader would come away from it with the assurance that the diminished second is a diatonic interval. (Read, checking for occurrences of the word diatonic.) Is this a good idea? In one limited sense the interval is diatonic, but in some other senses it certainly is not (see Diatonic and chromatic). Perhaps this needs some work.

Please share you opinion with us on Talk:Pythagorean comma. Do not answer here, because it would duplicate the discussion. This messagge will point the editors of this article to the other talk page. − Paolo.dL (talk) 22:16, 15 August 2010 (UTC)
