The previous disposition was oriented toward the generation of the modes,
all in the same (natural)Window,
with the 2 major modes together top-right and the 2 minor modes together bottom-left,
and with the 2 diatonic modes together top-left and the 2 chromatic modes together bottom-right,
the modes of the same direction being isolated in opposite corners.

This disposition will, on the contrary, be oriented toward the direction of the modes,
in 2 different Windows (natural and 3 flats),
around a centralTONIC chordwhich may be either major or minor,C(m),
with the 2flatteningmodes together above and the 2 sharpening modes together below,
and with the addition of theANTE-1at each end,
the two best known modes sharing the same DOMINANT and the same ANTE-1.

The2 Leading Tonesof the TONICFRAME, placed a minor second on either side,BandAb,
will be present above and below, in the DOMINANT and in the ANTE-1 chords.
They will be alternately diatonic and chromatic depending on the Window involved,
and the DOMINANT of one side will have aMetamorphosis 4relationship
with the ANTE-1 of the other side,
consisting of exactly the same notes, with inversion of thePrimary and Secondary Notes.

TheDm^7-5 chord deserves special attention if compared to theD⁷ , aVofV,
whoseF#is a Leading Tone of theGD FRAME, and not of theCG FRAME, as is theAb.
