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.

On the other hand, seconds, fourths and sevenths are highly informative.
In orgone, these scale degrees appear in the most consonant triads and tetrads of 11edo orgone, namely 8:9:11:15, 8:9:11:14 and 16:17:22:28. Those chords are therefore crucial for Orgone[7] modal harmony.

Modal harmony

The seven modes are, from brightest to darkest:

Nerevarine mode 6|0 LLSLSLS
Vivecan mode 5|1 LSLLSLS
Lorkhanic mode 4|2 LSLSLLS
Sothic mode 3|3 LSLSLSL
Kagrenacan mode 2|4 SLLSLSL
Almalexian mode 1|5 SLSLLSL
Dagothic mode 0|6 SLSLSLL

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.
