| Interval information |
The la brea second is a 5-limit interval measuring about 161¢. It is the difference between 27/20 and 40/27, as well as 9/8 lowered by two syntonic commas.
Tempering it out leads to rank-2 la brea temperament, which splits the octave into two ~27/20 intervals and generally tempers 3/2 very sharp (by more than 20¢). This means that five generators from the Zarlino generator sequence starting with 6/5 are tempered to one and a half octaves. Reasonable higher-limit extensions to this temperent probably exist.
Etymology
This interval was named by Tristan Bay in August 2024 in reference to the taric MOS scale pattern that can be formed from tempering it out.
