A large Consequent
The 2 swings involved here are of DOMINANT/TONIC nature,
one in theDiatonic MinorMode and the other in theDiatonic MajorMode,
the first with the chordsDm6/Am7, Dm6/Am7, Dm6/Am 7, Dm6/Am7
,numbered
w4444, and
the second with the chordsG7/C6, G7/C6, G7/C6, G7/C, numberedM4444,
with the Am7becoming C6, at chord 8, with aMetamorphosis 4,
these 2 chords even maintaining the same dispositions throughout the
evolution of the 16 chords.
The chords of Dm6being (on the average) a third higher than the chords of G7,
the 4 Performance lines end up by being a diatonic second higher in
theantecedent.
To indicate this example completely in themajormode,
the first 8 chords would be numberedM6*6*6*6*,
with the COUNTER/TONIC cells in theShadows, 3 notches higher in the Window,
and the last 8 chords remainingM4444.
M6*6*6*6* 4444
Only theM6*6*6*6*has a canonic beginning
which could easily be "filled in" by referring to bars 5-6-7.
TheM4444section was left complete to show the flow of the canonic lines,
but canonic entries could be produced by starting each performance Voice
on the newCOMMON TONE,
the note G (BTAS) in chords 9-10-11-12.
Both theantecedent and theconsequent used thePrimary Dispositionof the Performing Voices
wiith the ascending Orbit Line in the Bass Voice.
A large Antecedent
It is possible to invert each cell of the preceding example to produce weaker cells,
of a TONIC/DOMINANT nature,
the antecedent with the chordsAm7/Dm6, Am7/Dm6, Am7/Dm6, Am7/Dm6
, numberedw3333, and
the consequent with the chordsC6/G7, C6/G7, C6/G7, C6/G, numberedM3333,
with the Am7becoming C6, at chord 9, with a Metamorphosis 4.
Once again, to indicate this example completely in themajormode,
the first 8 chords would be numberedM7*7*7*7*7*,
with the TONIC/COUNTER cells in the Shadows, 3 notches higher in the Window,
and the last 8 chords remainingM3333.
M7*7*7*7* 3333
Only the antecedentM7*7*7*7*has a canonic beginning
which could easily be "filled in" by referring to bars 5-6-7.
The consequentM3333section was left complete to show the flow of the canonic lines,
but canonic entries could be produced by starting each performance Voice
on the newCOMMON TONE,
the note G (SATB) in chords 9-10-11-12.
Once again, both theantecedent and theconsequent used thePrimary Dispositionof the Performing Voices
wiith the ascending Orbit Line in the Bass Voice.
The last 8 chords, being numberedM3333,
confirm that this whole 16-chord example is a largeAntecedent
which could precede the previousConsequent example in a large 32- chord complete Antecedent-Consequent,
abbreviated
aA / cA, aC / cC.
You can probably fit these 2 musical examples in the height of the screen and play
one after the other.
