Questions: Voice Independence and Counterpoint by Ear

Question 1

A student writing two-part counterpoint starts by sketching the chord progression they want, then assigns notes to each voice to fit those chords. What is wrong with this approach according to the principles of counterpoint?

• A. Nothing — establishing harmonic structure first ensures the voices produce acceptable intervals
• B. It reverses the proper order: in counterpoint, voices move according to their own melodic logic and harmony emerges from their combination
• C. It is acceptable only if the student applies strict voice-leading rules when connecting chord tones
• D. It works for two voices but fails with three or more voices

Answer: (B)

This is the central misconception about counterpoint. Contrapuntal thinking is voices-first: each melodic line is composed to have its own compelling melodic identity — shape, rhythm, direction — and the harmonic intervals that result are emergent, not predetermined. Starting from a chord progression and filling in voices produces harmonized parts, not true counterpoint. The harmonic chord changes arise as a byproduct of independent voice movement, not as the organizing principle driving it.

Question 2

While listening to a Bach two-part invention, a student notices that the two voices frequently move in opposite directions. This contrary motion is best understood as:

• A. A technique for avoiding dissonance by keeping the voices physically separated
• B. An artifact of rules that forbid parallel perfect intervals
• C. Evidence of voice independence — each line pursues its own melodic trajectory, resulting in contrasting contours
• D. A way to emphasize harmonic changes by moving both voices to new chord tones simultaneously

Answer: (C)

Contrary motion is one of the clearest audible signs of voice independence: the two lines are not moving as a unit but following their own melodic trajectories. When voices move in contrary motion, each line has its own contour and direction, making them perceptually distinct. While contrary motion also helps avoid parallel fifths and octaves, the deeper reason it characterizes good counterpoint is that it reflects genuine melodic independence — both voices are behaving as separate melodies, not as harmonic parts.

Question 3

In well-composed counterpoint, the harmonic intervals between voices are determined by the independent melodic movement of each line rather than being chosen in advance.

• T. True
• F. False

Answer: True

This is the foundational principle of counterpoint as a compositional approach. The voices move according to their own melodic logic — shaping phrases, choosing smooth connections, maintaining characteristic rhythmic profiles — and the vertical intervals (thirds, sixths, dissonances, resolutions) result from that independent motion. This is why counterpoint is fundamentally different from homophonic writing, where voices are subordinated to a harmonic plan.

Question 4

A skilled listener who understands counterpoint should hear the two voices of a Bach invention as a unified single texture, since that is how the composer intended it to be experienced.

• T. True
• F. False

Answer: False

This reverses the listening goal for counterpoint. The perceptual skill required is figure-ground discrimination: the ability to hear each voice as a distinct melodic entity while also tracking their combination. Hearing counterpoint as a single undifferentiated texture means losing precisely the voice independence the composer worked to preserve. The trained ear can shift attention between voices, follow each one's melodic narrative independently, and then hear the whole. Losing individual voice identities in a blur of texture is a sign of insufficient contrapuntal listening.

Question 5

Why does the counterpoint principle 'voices first, harmony emerges' matter for ear training? What specifically are you listening for when analyzing two-part counterpoint by ear?

Model answer: Because harmony is emergent in counterpoint, you must listen to each voice as an independent melody — tracking its contour, rhythm, and motion — rather than just identifying chord labels. When analyzing by ear, you listen for: how each voice moves on its own (leaps, steps, rhythmic character, phrasing), how the voices relate in motion type (contrary, oblique, parallel, or similar), and how their independent movement creates dissonances and resolutions. The goal is sustaining awareness of two melodic streams simultaneously while remaining attentive to each.

The practical listening skill is selective auditory attention — the ability to focus on one voice without losing the other, then integrating both. This differs from listening for harmony, where you identify the chord at each vertical moment. In contrapuntal listening, the chord is secondary; what matters is how each voice earns its movement through melodic logic and how their independence produces both melodic interest in each line and harmonic tension-and-resolution in their combination.
