In 16-edo Diatonic scales played are dissonant because of the 25 cent raised superfourth in conjunction with the 25 cent subtracted fifth. The septimal semi diminished fourth can be more desirable. Perhaps using Moment of Symmetry Scales an alternative temperament families like the "Anti-Diatonic" Mavila (which reverses step sizes of diatonic), Diminished, Happy, Rice, Grumpy, Mosh, Magic, Lemba, Cynder, and Decatonic can be more interesting and suitable.

Like the conventional 12-tet diatonic and pentatonic (meantone) scales, these arise from tempering out a unison vector from Fokker periodicity blocks. Only in 16-EDO, that unison vector is 135:&lt;span class="text_exposed_show"&gt;128, instead of 81:80. Based on seeing a diagram by Erv Wilson showing the mapping of prime 5 as 3 steps in a chain of fifths- which is the mapping and generator required to produce octave-repeating scales where 135:128 vanishes&lt;/span&gt;.
