Questions: Smooth Voice Leading and Stepwise Motion

Question 1

The soprano voice has just leaped up a major sixth to a high note. According to smooth voice leading, what should most likely happen next?

• A. The soprano should leap again in the same direction to maintain melodic momentum
• B. The soprano should step down by a half or whole step, compensating the leap with contrary stepwise motion
• C. The soprano should hold the note for extra duration to give the arrival point emphasis
• D. The soprano should immediately leap back down to the starting pitch to restore balance

Answer: (B)

Classical compensation for a leap is stepwise motion in the opposite direction — not another leap, not holding the note, and not jumping back. This creates melodic balance: the voice reaches an extreme point and then steps back naturally. Leaping back to the starting pitch (option D) would create a melodic hiccup, not a smooth line. The compensation principle applies because uncompensated leaps make lines sound disjunct and difficult to perform; stepwise return after a leap is what gives the gesture its arc.

Question 2

Why is stepwise (conjunct) motion the default preference in vocal writing?

• A. Because the human voice cannot reliably sing intervals larger than a minor third in tune
• B. Because stepwise motion automatically prevents parallel fifths and octaves between voices
• C. Because the ear tracks stepwise lines effortlessly, making them singable, easy to follow, and melodically coherent
• D. Because stepwise motion always achieves smooth common-tone connections between adjacent chords

Answer: (C)

Stepwise motion is preferred because it is the most natural and singable — the voice moves in the smallest available increments, and the ear follows the melodic contour without effort. This has nothing to do with preventing parallel intervals (option B), which is a separate concern addressed by other voice-leading rules. Singers can sing larger intervals accurately with preparation, but the default preference for steps reflects the cognitive ease and expressiveness that smooth motion produces in performance.

Question 3

An inner voice that holds the same pitch through several chord changes is demonstrating good voice leading, because it avoids disruptive leaps.

• T. True
• F. False

Answer: False

A voice that fails to move is not demonstrating good voice leading — it is not truly functioning as a voice at all. The goal of smooth voice leading is not merely to avoid leaps, but to ensure that every voice is independently meaningful as a melody. An inner voice that simply repeats a note or stays static is harmonic filler wearing the costume of a line. The standard is singability: can you extract that voice and hear a purposeful melodic shape? A static inner voice fails this test.

Question 4

When two adjacent chords share a common tone, efficient voice leading typically holds that tone in the same voice rather than moving it.

• T. True
• F. False

Answer: True

Common-tone retention is a central technique of efficient voice leading. When a note appears in both chords, the smoothest connection is to keep it in the same voice — this minimizes overall voice motion and maintains clarity. Moving a common tone to a different voice would require another voice to move further to compensate, increasing the overall distance traveled. In chorale-style writing, holding common tones while moving other voices by step is the textbook approach to smooth, efficient progressions.

Question 5

What does it mean for every voice in a four-part texture to be 'independently meaningful as a melody,' and how does smooth stepwise motion help achieve this?

Model answer: Each voice should have a sensible melodic shape — a direction, contour, and arrival points — that makes sense on its own if extracted from the texture. Smooth stepwise motion achieves this by ensuring each voice moves purposefully through intervals the ear can follow, rather than leaping randomly or hovering on repeated notes. If the soprano, alto, tenor, and bass lines each function as singable melodies with their own shapes, the four-part texture has true melodic independence rather than one melody supported by harmonic filler.

This is the deeper purpose behind the preference for stepwise motion — not just following a rule, but achieving the genuine four-voice texture that distinguishes counterpoint from melody-plus-chords. In practice, this means treating inner voices (alto and tenor) with the same compositional attention as the outer voices (soprano and bass), giving them their own momentum and arrival points rather than letting them drift wherever the harmony permits.
