Questions: Harmonic Function: Tension and Resolution

Question 1

A student claims: 'Both the ii and V chords are non-tonic, so they create the same amount of tension and the same urgency to resolve.' Which response best corrects this?

• A. The student is correct — all non-tonic chords have equal tension by definition
• B. Actually the IV chord is the most tense because it is furthest from I in the circle of fifths
• C. The V chord has the strongest pull to I because it contains the leading tone (7̂) and scale degree 2̂, two notes that pull toward tonic in opposite directions — the ii lacks this specific urgency
• D. Tension is entirely subjective and cannot be compared between chords

Answer: (C)

The V chord's distinctive urgency comes from two simultaneously active tendencies: the leading tone (7̂) pulling upward by half step to 1̂, and the fifth of the chord (2̂) pulling downward by step to 1̂. These contrary pulls converge on the tonic, creating the characteristic dominant tension. The ii chord is pre-dominant — it prepares V — but lacks this specific dual-voice convergence. Not all non-tonic chords are equally tense.

Question 2

A V6 chord (first-inversion dominant, with the leading tone in the bass) is considered more tense than a root-position V chord because:

• A. First inversions always produce more dissonance than root-position chords in tonal music
• B. The leading tone in the bass has a strong upward pull toward tonic, making the bass itself directionally active and increasing the chord's instability
• C. V6 contains a minor third interval that is more dissonant than the major third in root-position V
• D. First-inversion dominant chords cannot resolve to tonic and create a sense of permanent irresolution

Answer: (B)

When the leading tone appears in the bass voice, it adds directional momentum to the bass line itself: B in the bass (in C major) strongly pulls upward to C. Root-position V has a stable fifth in the bass, which can more easily be sustained. V6 amplifies the tension by engaging the bass in the resolution drive. This is a practical example of why chord inversions matter beyond mere label differences.

Question 3

The ii chord typically functions as pre-dominant in a tonal progression, setting up the approach to V rather than moving directly to I.

• T. True
• F. False

Answer: True

The subdominant function (IV and ii) sits between tonic stability and dominant tension. In the standard ii–V–I or IV–V–I progression, the pre-dominant chord intensifies the approach to V, which then resolves to I. This three-stage traversal — pre-dominant, dominant, tonic — is the most complete form of tonal motion and appears in Bach chorales, Classical sonatas, and jazz standards alike.

Question 4

The cadential 6/4 chord (V⁶₄, second inversion of V) functions as a stable, independent dominant chord capable of providing harmonic support at a cadence.

• T. True
• F. False

Answer: False

The V⁶₄ is so unstable that it functions almost as an ornamentation of V rather than an independent chord. The fourth and sixth above the bass — dissonances created by the inversion — must resolve downward by step to the third and fifth of V, and then V resolves to I. V⁶₄ is better understood as a delayed arrival at V, not a standalone dominant. Students who label it as stable dominant harmony miss its actual voice-leading function.

Question 5

Explain why the V7 chord creates even stronger tension toward tonic than the plain V chord, using what you know about the leading tone, scale degree 2̂, and the new seventh.

Model answer: The V chord already contains two tones pulling toward tonic: the leading tone 7̂ pulling up by half step to 1̂, and the fifth of the chord 2̂ pulling down by step to 1̂. Adding the seventh creates a third directionally active tone: in the key of C, the V7 is G–B–D–F, and F (scale degree 4̂) pulls downward by half step to E (scale degree 3̂ of the tonic chord). Now three pitches have specific resolution tendencies toward tones of I. Additionally, the interval between the third (B) and seventh (F) of V7 is a tritone — a highly dissonant interval that demands resolution. V7 is thus more tense than V because it has more simultaneous unresolved tendencies pressing toward tonic.

The progression from V to V7 is a good illustration of how added dissonance increases harmonic tension without changing function. Each added unstable element is another 'vote' for resolution, making the pull toward tonic more urgent. This is why V7 is the default dominant in common-practice music — it rarely needs more justification than its inherent instability.
