This scale can be thought of as a MOS generated by 5/2-equivalent jubilic temperament where [[50/49]] vanishes. This is one of the most simple no-threes temperaments, although in this case it is using the second-best period choice of 5/2 rather than 2/1, causing strict MOS to be generated rather than multi-MOS. The bright generator of the MOS represents [[7/5]]~[[10/7]] and the dark generator represents [[7/4]]~[[25/14]]. This gives 5L 3s⟨5/2⟩ many approximations of 4:5:7 chords. | This scale can be thought of as a MOS generated by 5/2-equivalent jubilic temperament where [[50/49]] vanishes.
