~~Oceanfront~~ is ~~very similar to~~ the ~~familiar 7-limit superpyth~~ temperament, ~~in which 16~~/9 is ~~equated with 7~~/4, ~~32/27 equated with~~ 7/6~~, and 81~~/64 with 9/7. ~~Oceanfront aims to equate 81/64 with 13/10 instead, however, so the fifths are even sharper than those~~ of ~~superpyth - 713.910 cents is~~ the ~~optimal POTE generator. The general structure of this scale is similar to~~ that ~~of meantone[~~7], ~~except that the "major" triads~~ in ~~this scale are 10:13:15, and the minor triads are 6:7:9~~.

Tropic is the merger of the biosphere and the archipelago. It is also a subgroup relative of semaphore temperament, since 49/48 vanishes. Of note is that 676/675 vanishes, so that two 7/6's (or 15/13)'s is equated with 4/3. While this temperament doesn't take advantage of the nearly pure harmonies that biome tempering can offer, particularly where 7/4 is involved, it still has some use, particularly for those who don't mind a bit more error in their tunings.

The sharp fifths of this scale can be a little more dissonant than meantone ears are used to, as can the flat fifths of something like mavila. This scale is very much like a brighter cousin of mavila in that regard.

-Oceanfront is very similar to the familiar 7-limit superpyth temperament, in which 16/9 is equated with 7/4, 32/27 equated with 7/6, and 81/64 with 9/7. Oceanfront aims to equate 81/64 with 13/10 instead, however, so the fifths are even sharper than those of superpyth - 713.910 cents is the optimal POTE generator. The general structure of this scale is similar to that of meantone[7], except that the &amp;quot;major&amp;quot; triads in this scale are 10:13:15, and the minor triads are 6:7:9.&lt;br /&gt;
+Tropic is the merger of the biosphere and the archipelago. It is also a subgroup relative of semaphore temperament, since 49/48 vanishes. Of note is that 676/675 vanishes, so that two 7/6's (or 15/13)'s is equated with 4/3. While this temperament doesn't take advantage of the nearly pure harmonies that biome tempering can offer, particularly where 7/4 is involved, it still has some use, particularly for those who don't mind a bit more error in their tunings.&lt;br /&gt;
