Chapter 17-harmonic Sequences

Question 1

Writing Sequences guidelines

Answer 1

Guideline 1: The voice leading in the model and first copy must be correct. Because the copies merely restate the model (at a different pitch level), any faulty voice leading in the opening will blemish every copy.
Guideline 2: Write outer voices first. Try to incorporate contrary step motion between them and include at least one imperfect consonance.
Guideline 3: Prepare and resolve each chordal seventh.
Guideline 4: When you write Sequences involving inverted seventh chords, make sure each sonority is complete.

Question 2

Rules for 7th chords in sequences

Answer 2

They must be prepared and resolved if they are used. Similar to the rules of suspensions.

Question 3

Descending second, descending-third, ascending second,

Question 4

Answer 4

Model and copy

Question 5

Model

Answer 5

The initial pair of chords that form the basis for sequential repetition.

Question 6

The repetition of the two-chord model in a harmonic sequence at a given ascending or descending interval.
