Dominant seventh chord: Difference between revisions

Line 15:

* 36:45:54:64 (1⁄1–5⁄4–3⁄2–[[16/9|16⁄9]]), the the [[Ptolemaic dominant seventh chord]], is found on the dominant scale degree ([[3/2|3⁄2]] or V) of [[Ptolemy's intense diatonic scale (Zarlino)|Zarlino]], perhaps the most common 5-limit diatonic.

* 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 rooted at ~~[[5/4|5⁄4]]~~ (~~III~~) and ~~[[15/8|15⁄8]]~~ (VI) in the [[duodene]].

* 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 rooted at 1⁄1 (I) and 4⁄3 (IV) 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 (V) 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]].
