'''Electra''' is a [[tritave]]-repeating rank-2 temperament in the 3.5.11.13 subgroup, with a generator near [[15/11]] or its tritave complement, 11/5. The name was given by [[User:CompactStar|CompactStar]] in analogy to [[Sirius]], [[Arcturus]], and [[Canopus]], which are tritave-repeating temperaments named after stars. It tempers out 14641/14625 (the amount by which three 11/5's exceed 117/11) and 1875/1859. It possesses MOS scales of the families {{mos scalesig|4L 3s<3/1>|link=1}}, {{mos scalesig|7L 4s<3/1>|link=1}}, and {{mos scalesig|7L 11s<3/1>|link=1}}.


'''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 comma  14641/14625, the amount by which 3 11/5's exceed 117/11. It possesses MOS scales of the families [[4L 3s (tritave-equivalent)|4L 3s<3/1>]], 7L 4s<3/1>, and 7L 11s<3/1>.

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.  
[[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]].
