Chapter 4: Part-writing and non-chord notes Flashcards
What is part-writing?
Arranging a four voice texture piece to maximise the use of chords.
What is similar motion?
Both voices move in the same direction.
Why is similar motion bad for part-writing?
It is very disjunct and lacks independence.
Why is contrary motion better for part-writing?
It allows the soprano to gain independence from the bass and results in smaller leaps.
What is the common disjunct rule in part-writing?
Have as much conjunct movement as possible with very small disjunct.
What should be done if disjunct in the melody is inevitable?
Ensure the note after such a leap returns within the span of the interval.
What are the part-writing rules for inner voices (alto + tenor)?
Try to keep conjunct movement or frequently stay on the same note, with no more than leaps in 3rds.
How can a good texture be achieved?
Keep upper parts close together and maintain a sizeable gap between bass and tenor for independence.
Which degree of the triad is repeated in four voices texture?
The tonic.
What does traditional harmony ban?
Parallel 5ths and parallel octaves between any of the four voices.
What is oblique motion?
One part stays on the same pitch while the other part moves up or down.
What is an example of a tendency note?
Leading note.
What are non-chord notes?
Additional notes to provide rhythmic movement and a better sense of melodic flow.
What is a passing note?
A note that can be inserted to fill in the gap with stepwise movement where there is a leap of a 3rd.
What is an unaccented passing note?
Notes that don’t come on the beat and fill the gaps between the chord notes.
