Metamorphosis 2 is usually presented closed, in either form (first or last).
         The chord changes:
                   - its direction;
                   - its position in the series of fifths (1 FRAME away);
                   - the swing to which it belongs;
                             (2 fifths away - with the metamorphosed chord in interior positions);
                   - the note which acts as Orbit 0 (the COMMON TONE);
                   - Orbit 2 and Orbit 3 replace each other,
                             - the note which was Orbit 2 becomes Orbit 3 and that which was Orbit 3 becomes Orbit 2.

-We have here the following chords:
         C⁶ - with a Substitution 1(3), followed by the MOTRIX A, in the Alto;
         G⁷¹ Dm⁶⁵- Metamorphosis 2 - with a Substitution 1(0), in the Bass
                   which removes both the G, Orbit 0 of G⁷¹ and the A, Orbit 0 of Dm⁶⁵.
                   Each of these two notes serves as Orbit 0 on one chord and
                             as a Non-chordal Tone of Orbit 0 on the other.
                   By having the chord Incomplete we avoid this incompatibility altogether.
         Am⁷ - with a Substitution 1(3), followed by the MOTRIX G, in the Soprano;
         Dm⁶⁵ G⁷¹- Metamorphosis 2 - with a Substitution 1(0), in the Tenor.
The chords of Rest (on the Beat), C⁶ and Am⁷, were first presented as Real Triads
         to differentiate them from each other.
