Questions: Passing Tones and Neighbor Tones: Melodic Decoration

Question 1

In a melody over a C major chord (C–E–G), the melody moves E → F → G. What type of non-chord tone is the F, and why?

• A. Neighbor tone — F steps away from E and returns to E
• B. Passing tone — F moves by step between two chord tones, E and G
• C. Chord tone — F is in the key and belongs to the harmony
• D. Suspension — F is held over from the previous chord before resolving

Answer: (B)

A passing tone moves by step between two different chord tones — it 'passes through' on the way from one to the other. Here E (chord tone) → F (non-chord tone) → G (chord tone) is a classic passing tone: F fills in the step between E and G, both of which belong to the C major chord. A neighbor tone, by contrast, steps away and returns to the *same* pitch. The F here is directional — it is going somewhere new — which is the defining feature of a passing tone.

Question 2

A composer writes the melody C → B → C over a C major chord, with B on a weak beat. What type of non-chord tone is the B?

• A. Passing tone — it passes between two different chord tones
• B. Suspension — B is held over and resolves down to the next chord
• C. Neighbor tone — it steps away from C and returns to the same C
• D. Escape tone — it moves by step and resolves by leap

Answer: (C)

A neighbor tone steps away from a chord tone and returns to that *same* chord tone. C → B → C shows the melody departing from C by a half step (lower neighbor) and returning to C. No new chord tone is being approached — the function is purely decorative, adding a small inflection to the sustained C. A passing tone would move from one chord tone to a *different* chord tone, with the non-chord tone bridging the gap. The B here is a lower neighbor tone.

Question 3

Both passing tones and neighbor tones typically occur on strong beats to give them harmonic emphasis.

• T. True
• F. False

Answer: False

Both types occur on *weak* beats — this is a defining characteristic. Placing a non-chord tone on a strong beat creates a dissonance where the harmony is most exposed, which sounds like a mistake rather than smooth decoration. The weak-beat placement is what makes passing and neighbor tones ornamental: the ear hears them as connecting gestures between the chord tones on strong beats. A non-chord tone on a strong beat that then resolves is a different device (suspension or appoggiatura), not a passing or neighbor tone.

Question 4

A non-chord tone in a melody usually indicates a harmonization error — the composer should have used a chord that makes the note consonant.

• T. True
• F. False

Answer: False

This is the core misconception the topic addresses: non-chord tones are intentional compositional tools, not errors. Passing tones and neighbor tones are used deliberately to create smooth, stepwise motion between chord tones — they are what makes melodies singable and flowing rather than arpeggiated and angular. Every tonal melody uses non-chord tones as decoration. The skill is using them correctly (on weak beats, moving by step, between chord tones) so they read as smooth decoration rather than unwanted dissonance.

Question 5

What is the functional difference between a passing tone and a neighbor tone, and what melodic situation calls for each?

Model answer: A passing tone connects two different chord tones by step — it passes through between them (e.g., E → F → G over C major). Use a passing tone when you want smooth stepwise motion between two chord tones a third apart. A neighbor tone steps away from a chord tone and returns to the same one (e.g., C → B → C). Use a neighbor tone when you want to add melodic decoration to a repeated or sustained pitch without moving to a new harmonic target. Both occur on weak beats, but their melodic destinations differ: passing tones go somewhere new, neighbor tones circle back.

The two devices solve different melodic problems. Passing tones enable smooth motion across a harmonic gap; without them, the melody would have to leap the third directly. Neighbor tones add life to stationary pitches; without them, a repeated note on a long chord would feel static. Together, they give the composer a vocabulary for decorating the harmonic skeleton with smooth, vocally natural motion.
