Questions: Integrating Passing Tones and Suspensions

Question 1

A tone appears on the first (strong) beat of a measure, clashes with the accompanying harmony, and then moves downward by step to a consonant note on the following weak beat. What is this tone?

• A. A passing tone, because it moves by step
• B. A suspension, because it appears on a strong beat as a dissonance and resolves stepwise downward
• C. A neighbor tone, because it returns to a chord tone after displacement
• D. An escape tone, because it moves away from the surrounding harmony

Answer: (B)

This is a suspension: strong-beat placement, dissonance with the underlying harmony, and downward stepwise resolution are its three defining characteristics. Passing tones also move by step, but they appear on weak beats and connect two chord tones — they don't create strong-beat dissonance. The strong-beat position is crucial: it gives the suspension its expressive weight, because the ear expects consonance on strong beats, making the dissonance feel like a delay of resolution.

Question 2

A student writes a passing tone between two chord tones in a melody, placing it on beat 1 of a 4/4 measure. What rule does this violate?

• A. Passing tones must always move upward, not downward
• B. Passing tones must connect non-adjacent scale degrees, not consecutive ones
• C. Passing tones belong on weak beats — a strong-beat dissonance functions as a suspension, not a passing tone
• D. Passing tones are not permitted in 4/4 time signatures

Answer: (C)

Passing tones are defined partly by their metric placement: they belong on weak beats, where they connect two harmonic tones by step without creating accented dissonance. Placing a dissonant tone on a strong beat (beat 1 in 4/4) turns it into something else — effectively a suspension — because the ear treats strong-beat dissonances as requiring formal resolution. The distinction between passing tones and suspensions is not just about the notes played but where they fall in the metric hierarchy.

Question 3

A suspension typically resolves upward by step to the next chord tone.

• T. True
• F. False

Answer: False

False. Suspensions resolve downward by step. This is one of their defining characteristics: the suspended note is held over from the previous beat, creating dissonance with the new harmony, and then falls by step to the expected consonance. Common figures include 4-3, 7-6, and 9-8. Upward resolution by step is characteristic of leading tones and certain appoggiatura figures, not suspensions.

Question 4

Passing tones and suspensions both add linear melodic interest without obscuring the underlying harmonic structure.

• T. True
• F. False

Answer: True

True. Both are non-harmonic tones embedded in a framework that keeps harmonic structure audible. Passing tones fill in stepwise motion between chord tones on weak beats, so the harmonic rhythm remains clear. Suspensions delay resolution but point directly toward the chord tone they are about to resolve to, making the harmonic destination clear even while momentarily suspended. Both serve melody without disrupting harmony.

Question 5

Explain why suspensions must occur on strong beats and resolve downward, while passing tones occur on weak beats.

Model answer: Suspensions depend on metric accent for their expressive effect: dissonance on a strong beat is heard as a delay of the expected consonance, creating tension that demands downward resolution. Passing tones are transitional — they connect two chord tones by step and need to be metrically unaccented so they don't disrupt the harmonic rhythm. Metric placement determines whether a non-harmonic tone functions as ornamental decoration (weak beat) or structural delay (strong beat).

The key insight is that metric placement isn't incidental — it determines the function of the non-harmonic tone. Strong-beat dissonances are heard as suspensions requiring resolution; weak-beat dissonances are heard as decoration. A tone in the 'wrong' position will sound like the wrong type of non-harmonic tone, which can confuse the listener's harmonic perception.
