[[23edo]] (469.57 cents) and [[41edo]] (468.29 cents): two tones represent 14/11 rather than 5/4, and J-O# (4 large steps + 1 small step) becomes a 5/3 rather than a 13/8. | [[23edo]] (469.57 cents) and [[41edo]] (468.29 cents): two tones represent 14/11 rather than 5/4, and J-O# (4 large steps + 1 small step) becomes a 5/3 rather than a 13/8. | ||
Using a pure 21/16 of 470.78¢ results in an extremely lopsided oneirotonic scale with L/s = 4.60 close to 5edo. Harmonically this results in a 9/8 of 212.342722 which is very much in the superpyth range (for comparison, 17edo's 9/8 is 211.765 cents). The "major tritone" in oneirotonic (J-N in Kentaku notation) will be a very flat fifth of 683.123 cents, constrasting with the very sharp 40/21 fifth (729.2 cents). | Using a pure 21/16 of 470.78¢ results in an extremely lopsided oneirotonic scale with L/s = 4.60 close to 5edo.

All these intervals contribute to the scale's overall shimmery quality. | ||
