Elkies | You didn't fully describe P,L,R; e.g. even assuming that P takes "X-major" to "X-minor" (or "x-minor" if you prefer) for each of the 12 X's, you didn't tell us what P does to any "X-minor". I guess that each of P,L,R is an "involution", i.e. each of PP,LL,RR is the identity, so for instance P takes each "X-minor" back to "X-major", and likewise L(E-minor) = C-major and R(A-minor) = C-major. Is this what you intend? [P and R would then stand for "parallel" and "relative" in the music-theory sense; I don't remember what L would be.] | |
