'''108:135:160:192''' is a [[dominant seventh chord]] found on the dominant scale degree (V or {{Frac|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]] ([[5-limit]]) major third with a [[16/9]] ([[3-limit]]) minor seventh, creating a [[64/45]] tritone between the two. Since each of the steps relates to at least one other by an interval in the [[9-odd-limit]], it is a 9-odd [[condissonant]] chord. | |||
Because this chord contains a [[40/27]] ''grave fifth'' instead of a [[3/2]] ''perfect fifth'', it has more dissonance than would be present in the closely-related [[36:45:54:64]]. | |||

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 (5-limit) major third with a 16/9 (3-limit) minor seventh, creating a 64/45 tritone between the two. Since each of the steps relates to at least one other by an interval in the 9-odd-limit, it is a 9-odd condissonant chord.
Because this chord contains a 40/27 grave fifth instead of a 3/2 perfect fifth, it has more dissonance than would be present in the closely-related 36:45:54:64.
In meantone temperament, this chord is tempered to be the same as 36:45:54:64 and 20:25:30:36.
