Metamorphosis 3 is usually presented closed, in the form common to both functions.
The chord changes:
- its direction;
- its position in the series of fifths (2 FRAMEs away);
- the swing to which it belongs;
(1 fifth away - with the metamorphosed chord in exterior position);
- the notes which acts as Orbit 0 (COMMON TONE) of both chord positions.
There are 2 orbit exchanges here:
- there is an exchange between Orbit 0 and Orbit 2
(the note which was Orbit 0 becomes Orbit 2 and
the note which was Orbit 2 becomes Orbit 0);
- there is an exchange between Orbit 1 and Orbit 3
(the note which was Orbit 1 becomes Orbit 3 and
the note which was Orbit 3 becomes Orbit 1).
In Metamorphosis 2, the Non-Chordal Tone of Orbit 0 was required on one of the chords
to make it exactly like the other.
In Metamorphosis 3, the Non-Chordal Tone of Orbit 0 is required on both chords
to make them exactly the same.
-We have here the following chords:
the complete Tetrad G7s2 F6p+4 - Metamorphosis 3 -
with a Non-Chordal Tone of Orbit 0 on each chord,
A on the chord of G7s2 (which is Orbit 2 of F6) in the Tenor, and
B on the chord of F6p+4 (which is Orbit 2 of G7) in the Bass,
the complete tetrad F6p+4 G7s2 - Metamorphosis 3 -
with a Non-Chordal Tone of Orbit 0 on each chord, Tenor and Soprano.
The chords of Rest (on the Beat), C6 and C+7, are presented as completeTetrads
to differentiate them from each other.
This will be all the more evident when the chords are Dominantized
