Questions: Non-Harmonic Tones and Dissonance Treatment

Question 1

A composer writes a 4–3 suspension but places it on a weak beat. What is the problem with this?

• A. Suspensions are only valid in the bass voice, not in upper voices
• B. The suspension loses its expressive weight — the dissonance must land on a strong beat to feel like a genuine tension requiring resolution
• C. A 4–3 suspension must always resolve upward, not downward
• D. Weak-beat placement automatically converts a suspension into a passing tone

Answer: (B)

The expressive force of a suspension comes from the dissonance landing on a strong beat, where it feels weighty and demands resolution. Placed on a weak beat, the dissonance passes by too quickly and loses the longing quality that defines the suspension. Rhythmic placement is not incidental — it is part of the suspension's definition.

Question 2

Which of the following best describes the voice-leading logic of a passing tone?

• A. It is prepared as a chord tone, held into the next chord as a dissonance, then resolved by step downward
• B. It arrives on a weak beat before the chord that harmonizes it, creating a brief clash
• C. It fills in the stepwise space between two chord tones, moving in one direction on a weak beat
• D. It leaves a chord tone by step, then leaps away in the opposite direction before resolving elsewhere

Answer: (C)

The passing tone's logic is purely linear: it creates melodic momentum by connecting two chord tones by step, always on a weak beat so it slides through without disturbing harmonic stability. Option A describes a suspension; option B describes an anticipation; option D describes an escape tone.

Question 3

A suspension is a non-harmonic tone that moves by step from one chord tone to another on a weak beat.

• T. True
• F. False

Answer: False

This description conflates the suspension with the passing tone. A suspension is prepared as a chord tone in the previous harmony, held over (suspended) into the new chord where it becomes a dissonance, then resolved by step — typically downward. Crucially, the suspension appears on a STRONG beat, not a weak one. That rhythmic placement is what gives it its expressive weight.

Question 4

Non-harmonic tones like passing tones and suspensions can only be identified by analyzing both their harmonic context (which chord is sounding) and their rhythmic placement.

• T. True
• F. False

Answer: True

A pitch that is dissonant with one chord but consonant with another may or may not be a non-harmonic tone depending on which chord is current. And distinguishing a suspension (strong beat) from a passing tone (weak beat) requires knowing the metrical position. Both dimensions — harmonic context and rhythmic placement — are necessary for correct identification.

Question 5

Why does a suspension need to be placed on a strong beat, and what happens to its expressive effect if it is placed on a weak beat?

Model answer: A suspension's emotional power comes from the dissonance arriving with weight and insistence — the strong beat forces the listener to feel the tension before the resolution arrives. On a weak beat, the dissonance flashes by too briefly to register as meaningful tension, and the delayed resolution that creates longing simply disappears. Strong-beat placement is what distinguishes the expressive suspension from an ordinary passing dissonance.

The suspension is one of the most expressive devices in tonal voice-leading precisely because it prolongs the moment of dissonance. The strong beat amplifies the tension; the resolution on the following beat satisfies it. This is the 'grammar' of the suspension — preparation (consonance), suspension (strong-beat dissonance), resolution (step down). Violating the rhythmic requirement collapses the expressive arc.
