'''3L 7s''' occupies the spectrum from 10edo (L = s) to 3edo (s = 0).

[[TAMNAMS]] calls this MOS pattern '''sephiroid''' (named after the abstract temperament [[sephiroth]]).
[[TAMNAMS]] calls this MOS pattern '''jenovic'''.


This MOS can represent tempered-flat chains of the 13th harmonic, which approximates phi (~833 cents). In the region of the spectrum around [[23edo]] (L = 3, s = 2) , the 17th and 21st harmonics are tempered toward most accurately, which together are a stable harmony. This is the major chord of the modi sephiratorum. Temperament using phi directly approximates the higher Fibonacci harmonics best.
