11/10: Difference between revisions

Restore some old discussions. -s-expressions in the opening section since learning about the basics of a JI interval shouldn't rely on that knowledge

11/10 is treated as a comma in edos 1, 2, 3, 5, and some very low accuracy temperaments such as [[Very low accuracy temperaments #Antietam|antietam]].  
It may be treated implicitly as a comma in JI scales that (for example) do not find [[11/8]] and [[5/4]] above the same degree, but usually it makes much more sense to use it as a generator, such as the aforementioned very accurate strategy of making it a third of [[4/3]], leading to scales that look like [[porcupine]] but whose harmonies can more accurately be explained in a number of ways depending partially on the exact tempering used. If you use a half-octave period you get [[echidna]], a [[hedgehog]] lookalike that detempers [[100/99]] and [[121/120]] and which efficiently and accurately finds [[11-limit]] and (no-13's) [[17-limit]] harmonies.

=== [[Exotemperament]]s ===
Some [[val]]s that temper it out are the [[patent val]]s of [[edo]]s 1, 2, 3 and 5. An example rank 2 [[exotemperament]] that treats it as a comma to be tempered out is [[Very low accuracy temperaments #Antietam|antietam]].
