Noticed the wiki doesn't have a page on hem yet, so copy pasting Scott Dakota's explanation of it on this user page so that I or someone else can reference this and write a proper main space page on it later.
Struck gold in the GS investigation of 37ed2 project: (11/8)^3 ~= 13/5 via 6656/6655, a very tight microtemperament comma, 0.26c. This feels like the inner sanctum secret trick inside 37ed2. Then found the second trick! (13/10)^2 ~= 22/13, via 2200/2197. Putting this all together in 2.5.11.13, this means that if we stack prime 11 a lot, we also get a huge amount of ~ 13/10 and 13/11 and 11/10 and 55/32 for free as well. The GS tweaks required to make these analogies overt are very small. Microtemperament grade tweaks. I'm amazed at how Platonic-ideal archetypal this GS is. This is perhaps the best no-prime-3 GS territory I've come across so far, because such low error and such a high proportion of concordant chords in the rendered scales. Hem GS: GS(11 11 13/605 11 5/1859 11 11 13/605) aka GS(11/8 11/8 832/605 11/8 2560/1859 11/8 11/8 832/605) gg: (88/5)^(1/9) 551.667c interval of duplication: 11/10 CS: 5 7 9 11 13 24 37 50 87 124 211 298 385 472 559 etc. Hem[37] is a super smooth rational detemper of 37ed2, and Hem[11] and [13] are also extremely well distributed and musical. For xenners into exploring no-prime-3 land but still into having a lot of alternative concordant chords on hand, this territory is about as good as it gets. https://scaleworkshop.plainsound.org/scale/iestQHpCn Hem[11] this is such a badass no-3's JI scale, remarkable https://scaleworkshop.plainsound.org/scale/jesgMz7oe Hem[13] equally badass cool https://scaleworkshop.plainsound.org/scale/jesV_Vb0i FYI the name Hem is a riff on Emka 24 & 37 temperament in 2.5.11.13 or 2.5.7.11.13, which leverages <6656/6655, 2200/2197> --- this all seems to be the key to 37ed2's magic -- Scott Dakota
