Its second rotation, 3:4:5, reportedly has a lower [[harmonic entropy]]. However, 3:4:5 is not typically considered to be consonant in counterpoint and some derived theories (but not necessarily modern pop or xenharmonic theory), as it is not only [[rooted interval|nonrooted]] but the fourth above the root contrasts and therefore wants to move to the missing major third.

It is also not considered to be stable in [[Shasavistic theory]] unlike 4:5:6.
