Questions: Suspensions, Appoggiaturas, and Voice-Leading Function

Question 1

A 4–3 suspension appears in a soprano voice over a dominant bass. The suspended fourth delays resolution to the third of the dominant chord. How does this affect the harmonic function?

• A. It weakens the dominant by introducing dissonance that distracts from the chord's identity
• B. It replaces the dominant with a passing chord for one beat
• C. It intensifies the dominant's pull toward tonic by prolonging the tension before the expected resolution
• D. It has no effect on harmonic function since it is only a surface ornament

Answer: (C)

The suspension does not weaken harmonic function — it concentrates it. By delaying the exact chord tone the listener expects most (the third of the dominant), the suspension creates focused tension directed at that pitch. When the fourth finally resolves to the third, the arrival is amplified by the waiting. The dissonance is preparation, not interference.

Question 2

What mechanically distinguishes an appoggiatura from a suspension?

• A. An appoggiatura is prepared as a chord tone and held into the next chord; a suspension arrives by leap
• B. A suspension is prepared as a chord tone and held into the next chord where it creates dissonance; an appoggiatura arrives by leap to a non-chord tone then resolves by step
• C. Appoggiaturas occur on weak beats; suspensions occur on strong beats
• D. Suspensions resolve upward; appoggiaturas resolve downward

Answer: (B)

The mechanical distinction is preparation vs. leap. A suspension is anticipated — the voice arrives at a note on a weak beat as a chord tone, then the harmony shifts beneath it, creating the dissonance. An appoggiatura arrives without preparation by leap directly to a dissonant note on a strong beat, then resolves by step. Both create tension that resolves, but the suspension's dissonance is expected while the appoggiatura's is abrupt.

Question 3

Suspensions and appoggiaturas undermine harmonic function by introducing dissonance that competes with the chord's identity.

• T. True
• F. False

Answer: False

Both devices strengthen harmonic function by emphasizing specific chord tones through the act of delaying or approaching them indirectly. A 4–3 suspension makes the resolution of 4 to 3 the most audible event in the phrase, reinforcing the dominant's pull. An appoggiatura at a tonic arrival makes that arrival the emotional payoff of the phrase. Dissonance here is preparation for a chord tone, which arrives with amplified significance — not competition with the harmony.

Question 4

Suspensions are most effective at cadential moments, where the harmonic function they intensify is already doing significant structural work.

• T. True
• F. False

Answer: True

The suspension's power comes from prolonging tension that the harmony has already established. At a cadence, the dominant's pull toward tonic is the strongest harmonic force in the phrase. A suspension before the cadential resolution extends that tension by one beat, making the tonic arrival feel more earned. Used mid-phrase on weaker harmonies, the effect is diluted — which is why composers reserve these ornaments for structurally significant moments.

Question 5

Explain why the dissonance in a suspension is better understood as 'preparation' than as 'interference' with the harmony.

Model answer: A suspension begins as a chord tone (the preparation), then is held as the chord changes beneath it, creating dissonance on a strong beat. This dissonance is not random — it is directed at a specific chord tone that has been deliberately delayed. When the suspension resolves (typically by downward step to the expected chord tone), the arrival is emotionally amplified by the tension that preceded it. The dissonance functions as a charge that the resolution releases: the listener is made to wait for a pitch they want to hear, and when it arrives, its significance is heightened.

This is why Aristotle — and later music theorists — describe expressive dissonance as creating expectation rather than disorder. The suspension focuses the listener's attention on the impending resolution. Without the tension, the chord tone arrives without fanfare; with it, the same note becomes the emotional payoff of the phrase. This intensifying function is also why overuse dilutes the effect: if every moment is tense, no arrival feels like a relief.
