Chapter 7 Contrapuntal Expansions of Tonic and Dominant: Six-three Chords

Question 1

Voice exchanges

Answer 1

If the soprano and bass note that are harmonic to each other swap pitch. So if B is soprano and A is bass, then A is soprano and then B is bass.

Question 2

Voice-Leading and doubling Ruels for I6 and V6

Answer 2

Keep common tones (unless you use a voice exchange, which often requires movement in multiple voices).
When possible, double the root (you can double the third or fifth if it smooths the voice leading).
Never double the leading tone, 7 (the third of the dominant chord).
If the bass is not doubled, choose one fo teh following spacing for first-inversion triads.
Double unison: Two voices share the same pitch at the unison.
Neutral position: two voices share the same pitch at the octave
Subordinate harmonies, especially those that neighbor, usually appear on metrically weak beats or parts of beats.

Question 3

Difference between a root position chord and a 63 inversion chord

Answer 3

The 6 3 inversion chord is less stable.
