| '''Electra''' is a [[tritave]]-repeating rank-2 temperament in the 3.5.11.13 subgroup, with a generator near [[15/11]] or it's tritave complement 11/5. The name was given by [[User:CompactStar|CompactStar]] in analogy to the [[Sirius]], [[Arcturus]], and [[Canopus]] star names used for other tritave-repeating temperaments. It tempers out the commas 14641/14625 (the amount by which 3 11/5's exceed 117/11) and 1875/1859. It possesses MOS scales of the families {{sl|4L 3s}}, {{sl|7L 4s}}, and {{sl|7L 11s}}.

| [[File:Electra chords.wav|thumb|Just 11:13:15 and 143:165:195 triads on A]] | |
| The 11:13:15 triad is a characteristic feature of many Electra scales, and has been suggeested by [[User:CompactStar|CompactStar]] as a fundamental sonority for no-2's music, due to being relatively consonant compared to other no-2's chords. There is also a "minor" version of this triad, 143:165:195. 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]].
