Modally, the highest to lowest [https://en.wikipedia.org/wiki/Entropy_(information_theory) 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 orgone modes. On the other hand, seconds, fourths and sevenths are highly informative, and fortunately, 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

Main article: Smitonic

The seven modes are, from brightest to darkest:

Nerevarine mode 2212121
Vivecan mode 2122121
Lorkhanic mode 2121221
Sothic mode 2121212
Kagrenacan mode 1221212
Almalexian mode 1212212
Dagothic mode 1212122

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 orgone modes. On the other hand, seconds, fourths and sevenths are highly informative, and fortunately, 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.
