Subject: 7-limit planar lattice via fractional monzos: attn Monz
This 7-limit 2401/2400 lattice can be approached via Joe's favorite
fractional monzos, and from that I think he could figure out how to do
planar 7-limit lattice diagrams pretty easily. If we represent a 7 by
(2400)^(1/4), we are representing it by |5/4 1/4 1/2>. My lattice
business is simply what you get if you use this for 7s, and stick the
result inside the plane containing the 5-limit lattice: the pitch
class for 3 is [1,0], for 5 is [0,1], and for 7 is [1/4,1/2].
From this, given any 5-limit Fokker block, you can find the
corresponding 7-limit object by adding all the 7-limit lattice
elements which fall in the range of the block. A Fokker block obtained
from 25/24 and 81/80 is 1, 10/9, 6/5, 4/3, 3/2, 5/3, 9/5. If I use the
same range on the 7-limit planar lattice, I end up with the following
scale of 28 notes, which as expected makes use of 2401/2400
approximations to obtain extra 7-limit harmony.
