2960edo is in[[consistent]] to the [[5-odd-limit]] and [[harmonic]] [[3/1|3]] is about halfway between its steps. Otherwise it is excellent in approximating harmonics [[5/1|5]], [[9/1|9]], [[11/1|11]], [[17/1|17]], and [[19/1|19]], making it suitable for a 2.9.5.11.17.19 [[subgroup]] interpretation, with optional additions of [[7/1|7]] and [[23/1|23]], or [[21/1|21]] and [[13/1|13]]. | 2960edo is in[[consistent]] to the [[5-odd-limit]] and [[harmonic]] [[3/1|3]] is about halfway between its steps.

The 2960dh [[val]] {{val| 2960 4691 6873 '''8309''' 10240 10953 12099 '''12573''' }} is the unique mapping that supports both the 80th-octave temperament called [[mercury]], and the coincidentally similarly named [[mercurial comma]], which is the difference between a stack of 5 [[19/17]] and 2 [[15/14]] with the octave | The 2960dh [[val]] {{val| 2960 4691 6873 '''8309''' 10240 10953 12099 '''12573''' }} is the unique mapping that supports both the 80th-octave temperament called [[mercury]], and the coincidentally similarly named [[mercurial comma]], which is the difference between a stack of 5 [[19/17]] and 2 [[15/14]] with the octave. These can be arranged in [[diatonic]] pattern to sound like a [[meantone]] scale. In this case, 19/17 is mapped to 474 steps and 15/14 is mapped to 295 steps. | ||
From a regular temperament perspective, this in 2960edo can be potentially realized as [[893edo|893]] & 2960dh temperament in the 19-limit, as it maps two generators to 19/17 and 2955 generators to 15/14, which is circularly equivalent to 5 steps down in 2960edo (2955 + 5 = 2960), corresponding to Phrygian and Locrian modes. Eliora proposes the name ''quicksilvertone'' for this regular temperament. | From a regular temperament perspective, this in 2960edo can be potentially realized as [[893edo|893]] & 2960dh temperament in the 19-limit, as it maps two generators to 19/17 and 2955 generators to 15/14, which is circularly equivalent to 5 steps down in 2960edo ({{nowrap|2955 + 5 {{=}} 2960}}), corresponding to Phrygian and Locrian modes.
