The Flashmob
The Flashmob is a collection of temperaments of different ranks that all temper out 12376/12375, the flashma, a 17-limit comma associated with precise systems that model high-limit JI.
Temperaments discussed elsewhere include:
- Minutes → 60th-octave temperaments#Minutes
- Mercury → 80th-octave temperaments#Mercury
Noletaland
Noletaland is described as 282 & 1323, and it combines the smallest consistent edo in the 29-odd-limit with the smallest uniquely consistent. It reaches 4/3 in nine generators (noleta-...) and tempers out the landscape comma (...-land). Noletaland reaches 13/11 in 2 generators, and 29/19 in 5. Then there's 44/25 in 4, and 152/115 in also 4.
