Talk:Pitch interval

Additional citations
Why, what, where, and how does this article need additional citations for verification? Hyacinth (talk) 23:45, 6 October 2010 (UTC)
 * Gee, I don't know, Hyacinth. It isn't flagged for this. I did flag it for relying on a single source. "Pitch interval" is an odd term in my experience, and it looks like it may be a personal invention of Michiel Schuijer, the author of the only cited source. It may nonetheless be a legitimate subject for an article, but it would be nice to know it is in general circulation, and not just one author's term for a concept usually covered by some other term.—Jerome Kohl (talk) 04:11, 7 October 2010 (UTC)
 * "Appropriate citations to additional sources"? Hyacinth (talk) 06:46, 7 October 2010 (UTC)
 * Erm, yes, I think that would be a more appropriate formulation. Is there a template for this that I don't know about? If so, by all means let us change it.—Jerome Kohl (talk) 18:18, 7 October 2010 (UTC)
 * Now a moot point as far as this article is concerned. I have found another source that uses this term, and added it.—Jerome Kohl (talk) 21:18, 7 October 2010 (UTC)

Equations are confusing (wrong?)
The last sentence: "Ascending intervals are indicated by a positive value, and descending intervals by a negative one" cannot be correct. Modular arithmetic is always positive. For instance (-1) mod 12 = 11.

Or, perhaps, this last sentence is a non-sequitur, making a true--but unrelated--comment about intervals, when the immediately preceding text/equation concerned classes.

But why is an article on "pitch interval" even broaching the topic of "classes" (a modular arithmetic concept)?

My suggestion for taming this confusion: dump the "Equations" section of this article and clarify the rest of the article by using the proper equations for defining "pitch intervals", in place. Then merge this article with the Interval class article, and place them in the setting of the Pitch class article, where the "Integer notation" is defined.
