A diploid dicot temperament must temper out at least two commas: one to equate | A diploid dicot temperament must temper out at least two commas: one to equate a pair of intervals to the semioctave, and one to equate another pair of intervals to the hemififth. As a result, diploid dicot temperaments must have at least 4 primes. | ||
There are few temperaments that follow specifically the diploid dicot archetype, and those that do are often the lucky intersection of a diploid and an (alpha-)dicot temperament; lucky, because it's possible that the intersection of such a pair of temperaments produces a new one that cannot be expressed through diploid dicot, or any kind of chain of fifths. | |||
=== Sruti === | |||
The intersection of septimal [[diaschismic]] and [[namo]], which equates all of 16/13, 27/22, 11/9 and 39/32 to the neutral third, 45/32 and 64/45 with the semioctave. It is not very good for a diaschismic extension. | |||
=== Semihemi === | |||
The intersection of [[hemififths]] and [[kalismic]] and [[barbados]], which maps 15/13 to the hemifourth, 49/40 to the hemififth, and 99/70 to the semioctave. It is quite accurate, and solid as a hemififths extension, where primes 5 and 7 are along the dicot chain, and primes 11 and 13 are along the diploid chain. | |||
