definition of triad[edit]

A triad is always a 3-note chord built in thirds. The previous wording of the article suggested that it could be a 3-note chord built in some other way. 3-note chords built otherwise are more accurately called tri-chords. Also, the article delved into some marginal information relating to triads but without citation. Because they were so tangential, I deleted them. I understand my changes were reverted once. I hope this clarification helps explain the changes I've made once again. Jordan 20:16, 28 May 2008 (UTC)

You can always find a simplistic definition either written by someone not well read on the subject, or by an author dumbing-down the subject for beginners. WP should not yield to the lowest common denominator of intelligence in deciding for restrictions based upon loss of information. (talk) 05:33, 12 February 2014 (UTC)

Diatonic and chromatic[edit]

The article uses the term "diatonic" without adequate explanation. This term, along with chromatic, is the cause of serious uncertainties at several Wikipedia articles, and in the broader literature. Some of us thought that both terms needed special coverage, so we started up a new article: Diatonic and chromatic. Why not have a look, and join the discussion? Be ready to have comfortable assumptions challenged! – Noetica♬♩Talk 06:20, 6 April 2007 (UTC)

Number of essentially different trichords[edit]

This is a fun exercise in combinatorics which I think would be an interesting wikipedia article (or section thereof). I think this article would be the most natural home for this topic. Then again, one can do the same for tetrachords etc but I don't think those are as useful. Btyner (talk) 03:10, 15 December 2007 (UTC)

I can't make out what the antecedent of the "this" is supposed to be in the above remarks. There are, of course, nineteen possible non-enharmonically, non-transpositionally equivalent triadic subsets of the chromatic scale. By calling triads "trichords" one would seem to be invoking the method of Allen Forte, however, who counts inversionally related pairs as single sets and thus gets only twelve of what he calls "trichords". Standard combinatorics simply says there are 12! / (3! 9!) three-membered subsets of a twelve-membered superset and nothing about transposition or enharmonic equivalence. You can easily reduce 12! / (3! 9!) in your head (without recourse to a calculator or to pencil and paper) to 10 x 11 x 2 = 220. This figure includes twelve positions of eighteen triads (12 x 18 = 216) and four positions of the augmented triad. TheScotch (talk) 08:31, 15 December 2007 (UTC)


What parts of this article need to be cleaned up and how? What is missing from the article? Hyacinth (talk) 13:20, 15 July 2008 (UTC)

Removed. Hyacinth (talk) 14:23, 10 March 2010 (UTC)

The image is incorrect[edit]

The image says, "major triad, major triad, diminished triad, augmented triad." This second triad is minor; this should be corrected. —Preceding unsigned comment added by (talk) 00:39, 15 January 2009 (UTC)

Done. Thanks for your comment.

So what is a "Primary Triad" then?[edit]

"Primary Triad" redirects to this article, but this article does not explain what a "Primary Triad" is. Can anyone oblige with a definition? (talk) 15:40, 10 December 2009 (UTC)

Done. Hyacinth (talk) 14:36, 13 December 2009 (UTC)

The image with the triangles is indecipherable[edit]

I've stared at it for three minutes and I understand nothing. (talk) 11:32, 9 April 2017 (UTC)
