Questions: Homophonic Texture and Voice-Leading with Melody

Question 1

In a homophonic chorale setting, the alto voice moves from one chord to the next. Compared to the soprano melody, the alto should generally:

• A. Move in parallel motion with the soprano to reinforce the melodic line
• B. Take large leaps to add harmonic interest in the middle of the texture
• C. Move by the smallest available step, hold common tones, and prioritize smooth voice-leading over melodic interest
• D. Mirror the bass line to create a balanced, symmetrical texture

Answer: (C)

Inner voices exist primarily to define harmony and move smoothly — their job is pure voice-leading. They can be rhythmically static or patterned, but their melodic interest is secondary. The melody (soprano) can leap where inner voices cannot. Parallel motion with the soprano (option A) risks parallel fifths or octaves and blurs voice independence; mirroring the bass (option D) similarly collapses distinct layers.

Question 2

A soprano melody leaps up a sixth and lands on a pitch that is a non-chord tone at a strong downbeat. Is this good homophonic voice-leading?

• A. Yes — the melody has complete freedom to land anywhere, including non-chord tones, as long as inner voices supply the harmony
• B. No — leaps of a sixth are categorically forbidden in soprano lines
• C. No — at structurally exposed moments like downbeats and cadences, the melody's structural pitches should be chord members
• D. Yes — downbeats can freely use non-chord tones because the strong metric position draws attention away from harmonic clashes

Answer: (C)

The melody has much greater freedom than inner voices and can leap where they cannot. But this freedom applies to motion *between* structural moments. At downbeats, cadences, and new chord arrivals, the melody's structural pitches must agree with the harmony — non-chord tones at these exposed moments create clashes. Between structural moments, passing tones, neighbor tones, and ornaments are welcome.

Question 3

Parallel fifths between the soprano and bass are especially problematic in homophonic texture because these outer voices form the most audible framework of the texture.

• T. True
• F. False

Answer: True

The soprano and bass are the outermost voices and define the harmonic and registral frame that the inner voices fill in. Parallel fifths between any pair of voices collapse two independent voices into one; between soprano and bass, this collapse is maximally audible. The soprano–bass pair is monitored most vigilantly in homophonic voice-leading precisely because it is most exposed.

Question 4

In homophonic texture, the melody has no more freedom of movement than the inner accompanying voices.

• T. True
• F. False

Answer: False

The melody explicitly has more freedom than inner voices. It can leap where alto or tenor cannot, delay or ornament its resolutions, and move through non-harmonic pitches between structural moments. Inner voices exist to support harmony and move smoothly; the melody's primary obligation is to be melodically compelling. The one constraint the melody cannot escape is agreement with the harmony at structurally exposed points.

Question 5

Why is contrary motion between soprano and bass generally preferred as a default in homophonic voice-leading?

Model answer: Contrary motion keeps the soprano and bass voices clearly independent — they move in opposite directions, which prevents them from collapsing into parallel motion that would merge two distinct layers into one. It also maintains balanced registral spacing: when the bass descends (opening the space), the soprano ascending keeps the texture open; when the bass ascends, the soprano descending prevents the voices from crowding together. The ultimate goal is one voice leading with others supporting, all moving with purposeful independence — contrary motion between the outermost voices is the surest default habit to achieve this.

The structural logic here is voice independence. Parallel motion risks parallel fifths or octaves, especially between the most exposed outer voices. Contrary motion is inherently safe from these errors and also produces a natural balance in how the texture expands and contracts, which is why it's taught as the default even though oblique and similar motion are sometimes correct.
