The only significant harmonic entropy minimum that is [[Rothenberg_propriety|proper]] is the decatonic scale itself ([[Diaschismic_family|pajara]][10]), in which the period is 7/5~10/7 (tempered to be the same interval), one generator down from that makes [[4/3|4/3]], and another generator down makes [[5/4|5/4]]. More than a few people think this is a beautiful scale that deserves a lot of investigation and use, with some going so far as to say it's the next step up from the diatonic scale that preserves the most desirable features of diatonic melody and harmony. Paul Erlich's original paper on this scale can be found at either of these links:

Improper harmonic entropy minima include [[Meantone_family#Injera|injera]] (which is similar to pajara except that 5/4 is now four generators '''up''' and no periods) and [[Diaschismic_family#Shrutar|shrutar]] (which is basically pajara with the generator divided in two).
