Chapter 9: Triads in 1st Inversion& Part Writing
| First-inversion triads are used for a number of purposes, including to smooth bass lines and to provide melodic motion in repeated chords |
First Inversion triads for smooth bass melodies
*Root position triads are considered "anchor chords" because they provide stability within a piece. But if every chord within a piece was written in root position, the bass would be jumping around too much to make the song flow well.
| If all chords were in root postion, the only way to keep the melodic line from jumping too much would be do go to adjacent chords. (V-vi, IV-V) |
First-inversion triads provide Melodic Motion
*First-inversion traids as well as giving a smooth bass line, give melodic motion to the bass melody
| Book Ex. in GM: I - I^6 - I |
Voice Leading in First-inversion triads
*Voice leading for major and minor traids:
- Double the soprano
- If not, double the bass.
NEVER double the leading tone (ex. in CM, never double b ) |
*Voice Leading for diminished first-inversion triads:
- Double the third (bass note)
- Or double 5th factor.
| Bass note is best, avoid melodic skips and try to move all melodic lines in a stepwise motion |
