Dominant seventh chord: Difference between revisions

Line 15:

* 20:25:30:36 (1⁄1–5⁄4–3⁄2–[[9/5|9⁄5]]), the [[major-minor seventh chord]], combines a major third with the [[consonant]] seventh that would be found in a [[ptolemaic minor seventh chord]] built on the same root. It is found on the minor chords rooted at [[5/4|5⁄4]] (III) and [[15/8|15⁄8]] (VI) in the [[duodene]].

* 108:135:160:192 (1⁄1–5⁄4–[[40/27|40⁄27]]–[[16/9|16⁄9]]) is found on the dominant scale degree if the second degree of the diatonic scale is tuned a comma lower than in Zarlino (10⁄9 instead of 9⁄8).

* [[108:135:160:192]] (1⁄1–5⁄4–[[40/27|40⁄27]]–[[16/9|16⁄9]]) is found on the dominant scale degree if the second degree of the diatonic scale is tuned a comma lower than in Zarlino (10⁄9 instead of 9⁄8), such as in left-handed [[nicetone]].

* 128:160:192:225 (1⁄1–5⁄4–3⁄2–[[225/128|225⁄128]]), the [[Neapolitan chord]], is found on the chords rooted at [[16/15|16⁄15]] (♭II) and [[8/5|8⁄5]] (♭VI) in the [[duodene]]. (Although 225⁄128 is often considered an augmented sixth rather than a minor seventh, in [[Meantone_family#Septimal_meantone|septimal meantone]] it is tuned identically to the [[harmonic seventh chord]].)
