| Chord information |
108:135:160:192 is a dominant seventh chord found on the dominant scale degree (V or 3⁄2) of a diatonic scale with the second degree tuned a comma lower than in Zarlino (10/9 instead of 9/8), such as in left-handed nicetone. It combines a 5/4 major third with a 16/9 Pythagorean minor seventh, creating a 64/45 tritone between the two.
Since it contains a 40/27 grave fifth instead of a 3/2 perfect fifth, this chord has more dissonance than would be present in the closely-related Ptolemaic dominant seventh chord (36:45:54:64).
