Pajara has fairly low accuracy overall, due to 5/4 and 7/4 necessarily being separated by 600 cents. This means that [[49/48]] and [[25/24]] are tempered to the same interval, and allows for a simple alteration to produce a "minor" harmonic chord with 6/5 and 12/7 by flattening the third and seventh the same amount. | Pajara has fairly low accuracy overall, due to 5/4 and 7/4 necessarily being separated by 600 cents.

Pajara has [[mos scale]]s of 10, 12, and 22 notes. The 10-note mos, Pajara[10] is notable for sharing a number of desirable properties with [[5L 2s|diatonic]], while having fundamentally different categories; a [[semifourth]] (~250 cents) is between the two qualities of the decatonic 2-step (so that it is neutral rather than interordinal with respect to that scale) for example. This mos and the LsssLsssss [[modmos]] are called the ''symmetric'' and ''pentachordal'' decatonic scales and were independently invented/discovered by [[Paul Erlich]] and [[Gene Ward Smith]]. They are often thought of as subsets of [[22edo]], without much loss of generality and accuracy. | Pajara has [[mos scale]]s of 10, 12, and 22 notes.
