Acting As Complement

MeloHarmony

The harmonic chord pattern, the "changes", must evidently be the same for both melodies.
          How else could they be heard together?
     Small variations could be possible when only one melody is heard,
               especially in the bass line of the accompaniment,
          but, in general, the MeloHarmony is constant.

MeloRhythm

Contrary to the MeloHarmony, the MeloRhythm should be complementary.
     1. The rhythmic Entities could be of different length, either shorter or longer,
          without neglecting the qualitative aspect
               of split-cellsF=F=and kinetic off-beatsK2M(forcode).
     2. The note-values could be of different length, either shorter or longer.
     3. Even the rhythmic level could be different, either smaller or larger.

MeloLines

The MeloLines should also be complementary,
     so that the two melodies do not trample on each other, using the same notes.
They should also respect the priority of the Lines,
      Orbit 3toOrbit 2,Orbit 2toOrbit 1,Orbit 1toOrbit 1,Orbit 0toOrbit 0, (forcode)
          which were previously established for theCounter Suject in the Fugue.

Having Its Own Value

Symmetry

Symmetry is, above all, a question of moderation, enough but not too much,
     hearing a melodic motif only once is insufficient,
     hearing it 2 or 3 times is accepetable,
     hearing it 4 times is abusive.

Langer Hinge

ALanger Hingeshould be placed in the center of each Entity
     in order to keep it "open" so as to "close" only at the end.
