The seven modes are, from brightest to darkest:

Modally, the highest to lowest entropy scale degrees (unison = 1) are:
* 2 and 7 (equally): .99 bits
* 4 and 5 (equally): .86 bits
* 3 and 6 (equally): .59 bits
If a scale degree is high entropy it tends to be the most informative on average; the modes that have this interval as major and minor respectively are roughly a 50-50 split. This tells us that unlike in the diatonic scale, thirds and sixths are the ''least'' informative in distinguishing smitonic modes. On the other hand, seconds, fourths and sevenths are highly informative.

== 18edo smitonic ==
My favorite 11edo smitonic modes are 6|0 (major analogue), 5|1 (minor analogue) and 0|6 (Freygish analogue).

===Modal harmony===
MODMOSes and chroma modification become more important. Use MODMOSes with SS = diminished mos3rd = 266.67¢. For example, rotations of LLLSLSS.
 
or 5L 1M 1S: LLMLLLS or LLSLLLM
 
Treat it as neutralized mavila antidiatonic?
