Questions: Suspension and Non-Harmonic Tone Resolution in Voice Leading

Question 1

A student writes a 7–6 suspension but the 7th above the bass appears without having been present in the preceding chord — it simply appears as a dissonance and then resolves down by step. Why does this not function as a proper suspension?

• A. It is a proper suspension — any dissonance that resolves down by step qualifies
• B. The preparation is missing: a suspension's dissonance is earned by the note having been consonant in the previous chord, which is what makes it expressive rather than simply wrong
• C. The resolution should have been upward, not downward
• D. 7–6 suspensions require the 7th to be in the soprano voice

Answer: (B)

Preparation is what distinguishes a suspension from arbitrary dissonance. When the suspended note was already consonant in the preceding harmony, the listener hears the 'collision' as purposeful — the note belongs to the previous chord and is being delayed. Without preparation, the dissonant pitch appears with no prior grounding, making it sound like an error that happens to resolve rather than an intentional, structurally meaningful delay. The three-stage formula (prepare, suspend, resolve) is not bureaucratic — the preparation is the source of the suspension's expressive power.

Question 2

In standard tonal voice leading, a suspended note must resolve downward by step. What is the perceptual logic behind this direction?

• A. Downward melodic motion is physically easier for singers and instrumentalists
• B. The suspended pitch is heard as a vestige of the previous chord — it is 'too high' for the new harmony and corrects itself by descending to the expected chord tone
• C. Upward resolution always creates parallel fifths with the bass voice
• D. The rule is purely conventional with no acoustic or perceptual basis

Answer: (B)

The suspension is heard as a pitch that the voice should have moved to the new chord tone but got 'stuck' at the previous note. Because the new harmony requires a note one step below, the suspended pitch is perceived as sitting above its correct destination. The downward step is not arbitrary — it is the direction that connects the delayed voice to where it should have gone from the beginning. The resolution corrects the delay by descending to the chord tone that 'should' have been there, releasing the accumulated tension.

Question 3

A suspension is defined by its held-over consonant pitch from the previous chord, which becomes dissonant when the harmony changes beneath it.

• T. True
• F. False

Answer: True

This is the defining structural feature of a suspension. The note itself does not change — it was consonant in the previous chord and the bass and other voices move, turning it into a dissonance. This is precisely the three-stage sequence: preparation (consonant in previous chord), suspension (now dissonant against the new chord), resolution (step down to the expected chord tone). The dissonance arises from the stability of the prior context being carried forward — which is what makes it coherent rather than arbitrary.

Question 4

A suspension may resolve either upward or downward by step, depending on which direction produces smoother voice leading in context.

• T. True
• F. False

Answer: False

Standard tonal practice requires downward resolution. Upward resolution is a rare exception reserved mainly for the leading tone (when suspended above the octave and resolving upward to the tonic), where the upward pull is exceptionally strong. Treating upward and downward resolution as equally available misunderstands the perceptual logic: the suspended pitch is heard as 'too high' for the new harmony — it corrects by descending, not by continuing to ascend. Allowing free-direction resolution treats the suspension as just any passing dissonance, losing its specific structural meaning.

Question 5

What makes a suspension different from simply playing a dissonant note that happens to resolve stepwise, and why does this distinction matter for voice-leading analysis?

Model answer: A suspension is prepared — the 'dissonant' note was consonant in the immediately preceding chord and is held over into the new harmony. This means the dissonance is not arbitrary: the listener has already heard the note in a stable context and understands it as a delayed voice rather than an error. A dissonant note with no preparation has no such grounding — it appears unexpectedly, making its stepwise resolution seem incidental rather than structural.

In analyzing Bach chorales, the preparation criterion is the analytical key that distinguishes suspensions from other non-chord tone types. If the note appeared in the previous chord as a chord tone, it is a suspension; if it appeared between chord tones without such preparation, it might be a passing tone, neighbor tone, or other non-harmonic tone type — each with different voice-leading implications. The preparation is what makes the suspension a planned, structurally meaningful event rather than a colorful accident.
