chapter nine Flashcards
It creates an unstable sonority due to the Perfect 4th ABOVE the bass note
SECOND INVERSION triads should not be used as a SUBSTITUTION for Root Position triads because:
Prolong the Dominant Chord
What is the function of a Cadential Six-Four Chord?
I 64 and V 64
The most common Passing Six-Four Chords are
I 64 and IV 64
The most common Pedal Six-Four Chords are
- MOTION OF THE BASS NOTES
- CHORDS SURROUNDING THE 2ND INVERSION
- CONTEXT OF THE 2ND INVERSION CHORD
What are the THREE things to consider when trying to determine the type/function of SECOND INVERSION triad
the 5th
In PART WRITING for SECOND INVERSION triads, what should almost always be doubled?
- omit the 3rd in 3 part writing (?)
- arpeggiated
-passing - pedal
- cadential
What are the FOUR types of SECOND INVERSION Triad
2nd inversion triads are NOT used as substitutes for the root position because the 2nd inversion of a triad has less stable sonority than either of the other 2 bass positions
the interval of p4 had been considered dissonant if the lowest voice in the texture was sounding the bottom pitch of the p4
- bass arpeggiation
6/4 chords come about with a ROOT position triad, a FIRST inversion triad, or both
cadential 6/4
- most common
I 6/4 resolves to V in root position, both share same root so they function in the same way - extends/prolongs DOMINANT FUNCTION
The I 6/4 and V are bracketed as V (count for 1 note) - the pair of chords together have a dominant function
passing 6/4
- bass notes move STEPWISE
- 2nd inverted triad harmonizes with the middle note of a 3 note scalar figure in the bass (?)
- typically falls on a WEAK BEAT and features SMOOTH VOICE LEADING!!
V 6/4- I 6/4
pedal 6/4
- move a 3rd and fifth of a triad up by step and back down by step to their assigned positions
- either I - IV 6/4- I OR V- I 6/4- V progression
- 6/4 chord is on a WEAK BEAT
- stepwise voice leading INTO AND AWAY from the 6/4 chord
