Archytas clan: Difference between revisions

Revision as of 01:43, 8 January 2022

The archytas clan (or archy family) tempers out the Archytas comma, 64/63. This means that four stacked 3/2 fifths equal a 9/7 major third. (Note the similarity in function to 81/80 in meantone, where four stacked 3/2 fifths equal a 5/4 major third.) This leads to tunings with 3s and 7s quite sharp, such as those of 22EDO.

Adding 50/49 to the list of commas gives pajara, 36/35 gives dominant, 16/15 gives mother, 126/125 gives augene, 28/27 gives blacksmith, 245/243 gives superpyth, 250/243 gives porcupine, 686/675 gives beatles, 360/343 gives schism, 3125/3087 gives passion, 2430/2401 gives quasisuper, and 4375/4374 gives modus.

Discussed under their respective 5-limit families are:

Mother → Father family #Mother
Dominant → Meantone family #Dominant
Augene → Augmented family #Augene
Porcupine → Porcupine family #Septimal porcupine
Pajara → Diaschismic family #Pajara
Blacksmith → Limma family #Blacksmith
Catalan → Kleismic family #Catalan
Modus → Tetracot family #Modus
Passion → Passion family #Septimal passion
Immunized → Immunity family #Immunized

The rest are considered below.

Superpyth

Main article: Superpyth

In the 5-limit, superpyth tempers out 20480/19683 (sayo comma). This temperament has a fifth generator of ~3/2 = ~710¢ and 5/4 is equated to nine generators minus 5 octaves. A weak extension bipyth (10cd&22) tempers out the same 5-limit comma as the superpyth, but with a half-octave period and the jubilisma (50/49) rather than the Archytas comma tempered out.
