Two notable harmonic entropy minima for this [[MOSScales|MOS]] pattern are [[Diaschismic_family|srutal/pajara]] and shrutar. They are both improper.  
Two notable harmonic entropy minima for this [[MOS scale|MOS]] pattern are [[srutal]]/[[pajara]] and [[shrutar]]. They are both improper.  


In addition to the true MOS form, LsssLsss, these scales also have an interesting near-MOS form, LssLssss, in which the period is the only generic interval represented by more than two specific intervals.
