blues seven and flatted seven
Musician Ellen Fullman says these terms are equivalent to harmonic seventh:
- "The harmonic seventh interval in just intonation is known popularly as the blues seven,or flatted seven."
- Ellen Fullman, "The Long String Instrument", MusicWorks, Issue #37 Fall 1987
- (The WP article, Blues, cites Fullman, but the link to the PDF file is dead. This link is to the google cache.)
- "The naturally occurring seventh partial in the harmonic series is flatter than the seven in equal temperament. This interval is known to musicians as the blues seven."
- Out of curiosity, I checked Grove (1980). The entries for "Harmonic seventh" and "Blue note" say no such thing. --Jtir (talk) 18:52, 19 July 2008 (UTC)
Merge with minor seventh
Should this article be merged with the minor seventh article? It seems to me that the harmonic seventh is just the most consonant version of the minor seventh.Composerjude (talk) 16:56, 23 February 2009 (UTC)
Composer Ben Johnston uses a small "7" as an accidental to indicate a note is lowered 49 cents
This is confusing. I suppose the point is that the harmonic seventh is 49 cents lower than 9:5. Based on the first sentence, the reader will wonder why the "7" doesn't mean 31 cents lower. I had to do some calculations to figure this out. 22.214.171.124 (talk) 04:24, 24 December 2009 (UTC)
- How is that fairly direct statement confusing? "Based on" which "first sentence" (the first of the article, paragraph, or the sentence directly preceding)? Hyacinth (talk) 13:12, 24 December 2009 (UTC)
This article defines the subject note as a relative 9.7 semitones while also stating that it is 1000 cents in the equal temperament. One of these statements must be false because they contradict each other. To exemplify, this logic is not consistent with the layout of the page pertaining to the inverse note, which states its inverse note as equally tempered to 200 cents and thus 2 semitones.
I believe this Harmonic 7th page was meant to have its equal tempered cents to be ~969 and its just intonation cents at 1000 due to this note being non-native to the modern chromatic scale. However, this would mean that the inverse note's page and a few others would have to be changed. If not, then this current page should have the 9.7 semitones in the top right box changed to 10 so that it is consistent with the page of the note's inverse. — Preceding unsigned comment added by 126.96.36.199 (talk) 21:00, 11 August 2014 (UTC)
- Say what? Intervals in (12 tone) equal temperament are always a multiple of 100 cents, by definition; and 1000 cents cannot be a just interval. (Well, 55:98 is 1000.02 cents, but I'm guessing that's not of interest here.) —Tamfang (talk) 04:55, 22 August 2014 (UTC)
- This article states that the equal tempered equivalent of the harmonic seventh is 1000 cents (it approximates it with the same interval as the minor seventh). Tne article on the septimal whole tone (the inverse) states that its equal tempered equivalent is 200 cents (it approximates it with the same interval as the whole tone or major second). Those add up to 1200 cents, an octave. The math checks out. The approximate "number of semitones" is just so that readers can get a sense of where the harmonic seventh proper (justly tuned, the octave equivalent of the 7th harmonic) falls in relation to more familiar equal tempered intervals. — Gwalla | Talk 18:06, 22 August 2014 (UTC)
