7L 11s⟨3/1⟩ is a 3/1-equivalent (tritave-equivalent) moment of symmetry scale containing 7 large steps and 11 small steps, repeating every interval of 3/1 (1902.0¢). Generators that produce this scale range from 528.3¢ to 543.4¢, or from 1358.5¢ to 1373.6¢.

Temperaments

7L 11s3/1 MOS scales can be used for the Electra temperament, in which three generators down is approximately 13/11 and one generator up is approximately 15/11. If 11:13:15 is treated as the fundamental sonority of no-2's music, then Electra can be viewed as the analogue to meantone and 7L 11s3/1 can be viewed as the analogue to the diatonic scale. If twos are admitted, the hard end of the Electra heptatonic spectrum can be viewed as the subharmonic version of Pythagorean/Classical tuning.
