Harmony Ch. 1-6 Flashcards
show the possible figured bass for 1st inversion triads
663, 63, most commonly 6
- fifth double is 633
- 3rd doubled is 863
T/F: In figured bass, an Arabic numeral must appear to indicate a note alteration of the 3rd.
False
when two voices move by contrary motion from one harmonic interval to the same harmonic interval
parallels by contrary motion. forbidden
when a second inversion chord appears between root position and first inversion of another chord
passing 64
I6-V64-I or IV-I64-IV6 or I-V64-I6, etc.
When simple harmonic intervals occur between the bass and tenor voices, limitations must be placed on how low they may occur. What are these low interval limits?
Bottom note for bass:
min6: G
tritone: B
3rd: c
2nd: e
These are the only limitations.
What is open and close position? What is not considered in determining these positions?
Simple interval between soprano and tenor voices is close position. Compound=open.
The bass voice is not considered.
occurs between any two adjacent voices where the lower voice has a pitch higher than the upper voice
crossed voices…not normally permitted
occurs when a lower voice moves to a pitch higher than the previous pitch in an upper voice, or an upper voice moves to a pitch lower than the previous pitch in a lower voice
overlapping voices…not normally permitted
direct motion that occurs when two parts move in the same direction producing the same harmonic interval, WITHOUT REGARD FOR QUALITY
parallel motion
Note: major third to a minor third is parallel motion
which notes should be doubled when writing triads in 4 parts?
generally, tonal notes. Modal notes may occasionally be doubled as a result of melodic line. Sometimes triple the root and omit the 5
why are inversions used?
to give the bass voice smoothness and variety
indirect motion that occurs when two parts move in opposite directions
contrary motion
What must be present to have a perfect authentic cadence?
Both chords in root position and the tonic scale degree appears in the soprano voice over the tonic chord. Occurs at final cadence
Note: for imperfect, either chord can be inverted, or root is not in soprano for tonic chord. Occurs most often at cadence points other than final
-same rules apply for plagal
what is the primary means of establishing a key?
to move from the major dominant triad to the tonic triad
when do plagal cadences usually appear?
often follow final authentic cadences to emphasize finality
