Perhaps the simplest method of making use of the barbados triad and other characteristic island harmonies is to strip things down to essentials by tempering the 2.3.13/5 [[just intonation subgroup]]. | |||

==== Crete ==== | |||
Crete is a strong extension of Barbados tempering out [[64/63]], thus mapping [[7/4]] to a stack of 4 semifourths, and favoring a flat semifourth near 1 step of [[5edo]]. It is a weak extension of [[archy]]. This is a somewhat peculiar temperament as most archy systems do not have interseptimals or equate them with septimal intervals as in [[oceanfront]], but crete can be used in [[34edo|34d-edo]], [[39edo|39d-edo]], [[44edo]], and [[49edo]] (with 34d and 39d often considered better than 34edo and 39edo's [[semaphore]] patent vals). Some other notable non-patent vals are [[54edo]] using its second-best 13/5 and [[93edo|93b-edo]]. Crete can be seen as a version of [[pseudo-semaphore]] with a singular mapping for 3, making pseudo-semaphore's flat fifth [[52/35]] and pseudo-semaphore's sharp fifth [[3/2]]. It was discovered and named by {{u|CompactStar}} in 2026. Since it is the combination of [[Archy]] (which is named after an Ancient Greek music theorist) and island, Crete is named after a Greek island. | |||
