Sixth shyness?

Why (1, ♭3, ♭5, ♮6), not simply (1, ♭3, ♭5, 6)? What suggests ♮6 ≠ 6 in this context? Sz. (talk) 21:10, 26 March 2019 (UTC)

B and A

Is Bb really an enharmonic of A? To my knowledge, "enharmonic" means "the same note." Check out the page on enharmonics: http://en.wikipedia.org/wiki/Enharmonically Bbb (double flat)is enharmonic to A, but not Bb. That is because there is a whole step between A and B, and Bb is a half step from B. Flatting Bb would bring it down to an A. Or you could say Bb is enharmonic with A#, but not A.

A♯ and B♭ are enharmonic. Why do you ask? Hyacinth (talk) 05:17, 5 April 2011 (UTC)

Diminished seventh root

• Taken from article

The dominant ninth theory has been questioned by Heinrich Schenker. He explained that although there is a kinship between all univalent chords rising out of the fifth degree, the dominant ninth chord is not a real chord formation.<ref>Schenker, Heinrich (1954).

<!--this really belongs in the seventh chords article, if anywhere

According to W.A. Mathieu, the terminology of diminished seventh chords is misleading and contradicts usage for other types of chords. Specifically, the chord called a "diminished seventh chord", and written Bdim7 or B°, "should" indicate a B diminished triad with a minor seventh note, if the regular system of chord naming was followed. But instead a diminished seventh chord is a diminished triad with a diminished seventh note. Because of this "mistake" of nomenclature new terms had to be invented to indicate a diminished triad with a minor seventh. This chord has become known as a "half-diminished seventh chord" or a "minor seven flat five chord", written Bø or Bm7^(-5).

For all other types of chords a letter by itself indicates a major triad (for example, C means "C major triad"), while "min", "dim", etc, indicate a different type of triad (for example, Cmin means "C minor triad" and Cdim means "C diminished triad"). The number "7" by itself indicates the addition of a minor seventh note (C7 means "C major triad plus a minor seventh note"), while other types of sevenths are indicated with terms like "maj" (CMAJ7 means "C major triad plus a major seventh note"). Following this system, the term Cdim7 would mean "C diminished triad plus a minor seventh", but instead it means "C diminished triad plus a diminished seventh". Thus the terms "half-diminished", the ø icon, and "minor seventh flat five" (written m7^(-5)) were collectively invented to describe the chord whose "logical name" was already used.<ref>Mathieu, W.A.

Citation not needed

The whole wikipedia is overfull of "citation needed" tags. Use them when you think there actually is a citation, not wherever you see a "some do this some do that" pattern. This worsens readability and it's unclear whether a citation for the said sentence really exists. In the article, the sentence about notation could not be more precise IMHO. — Preceding unsigned comment added by 94.160.134.42 (talk) 07:25, 18 October 2011 (UTC)

Diminished 7th tuning

The tuning given in this page uses the MINOR 7th interval instead of the DIMINISHED one: "25:30:36:45". Diminished 7th interval should be 128:75 or 216:125 [see ] (which corresponds to approx' 25:30:36:43, [or 75:90:108:135 or 125:150:180:216]). Don't know which one is more widely accepted, but the tuning listed now is just wrong. — Preceding unsigned comment added by 82.166.81.221 (talk) 22:53, 18 January 2014 (UTC)

I reckon 25:30:35:42 is a more appropriate voicing. I don't know if I should replace with it or merely add it. TreeNamedUser (talk) 01:24, 24 January 2024 (UTC)

"Offensive" quote?

User:2601:243:700:BA00:D93A:9D4C:9109:777B is wishing to remove the following text from the Schoenberg quote: "There it remains, as a sentimental expression of sentimental concerns. It became banal and effeminate." on the grounds that it is offensive. Thoughts? It's certainly dated language, but I don't think the quote is complete without it. WP:NOTCENSORED, among other things.
