Resolution

In AP Music Theory, resolution is the movement of a dissonant tone or harmony to a consonant one, releasing tension and creating closure. Tendency tones like the leading tone and chordal seventh have specific required resolutions (leading tone up to tonic, seventh down by step) in common-practice voice leading.

What is Resolution?

Resolution is what happens when an unstable, dissonant sound moves to a stable, consonant one. Think of dissonance as a question and resolution as the answer. Common-practice music (the 18th-century style the AP exam tests) is built on this constant cycle of tension and release.

The exam cares most about resolutions that follow strict rules. The leading tone (scale degree 7) resolves up by half step to tonic, especially in outer voices. The chordal seventh resolves down by step. Non-chord tones like suspensions resolve down by step after being prepared, while retardations resolve up. When you part-write a V7 to I progression, you're really just managing two resolutions at once, the leading tone pulling up and the seventh pulling down. Get those two notes right and most of the chord writes itself.

Why Resolution matters in AP Music Theory

Resolution sits at the heart of the voice-leading units of AP Music Theory (Units 4-7), where you harmonize melodies, realize figured bass, and write four-part progressions following 18th-century procedures. Every cadence you label, every suspension you identify, and every V7 chord you spell correctly depends on knowing what resolves where. It also connects to the broader course skill of hearing and explaining tension and release, which shows up in aural questions about cadences and embellishments. If you can predict how a dissonance must resolve, you can answer melodic dictation, harmonic dictation, and part-writing questions faster because the music becomes predictable instead of random.

How Resolution connects across the course

Leading Tone (Units 1, 4-7)

The leading tone is the most famous tendency tone, a half step below tonic and itching to resolve up. On part-writing FRQs, an unresolved leading tone in an outer voice is one of the most commonly deducted errors.

Chordal Seventh Resolution (Units 4-7)

The seventh of any seventh chord (like the F in a G7 chord in C major) must resolve down by step. This single rule explains why V7 to I progressions move the way they do and why parallel motion errors often trace back to a mishandled seventh.

Nonchord Tones (Unit 6)

Suspensions, retardations, appoggiaturas, and other embellishments are defined by how they resolve. A suspension is prepared, sustained into a dissonance, then resolved down by step. Change the resolution direction to up and you've got a retardation instead.

Cadence (Unit 4)

Cadences are resolution scaled up to the phrase level. A perfect authentic cadence feels final because the dominant's tendency tones resolve cleanly into the tonic triad. Weaker cadences feel weaker partly because those resolutions are softened or avoided.

Is Resolution on the AP Music Theory exam?

Resolution shows up everywhere but rarely as a vocabulary question. On multiple choice, you'll identify non-chord tones by their preparation and resolution patterns, like distinguishing a suspension (resolves down) from a retardation (resolves up), or an escape tone from a neighbor tone based on how each leaves and returns. On the free response section, the part-writing questions are where resolution really gets graded. The 2025 SAQ Q7, for example, asked for a bass line following eighteenth-century voice-leading procedures, which means correctly resolving leading tones and chordal sevenths is baked into the rubric. Practice questions also probe how anticipations and other embellishments interact with cadential resolution, so know how each non-chord tone behaves, not just its name.

Resolution vs Cadence

Resolution is the general process of any dissonance moving to a consonance, and it can happen anywhere in a phrase. A cadence is a specific harmonic formula at the end of a phrase (like V to I) that creates closure. Cadences rely on resolution, but a suspension resolving in measure 2 is a resolution with no cadence in sight. If the question asks where the phrase ends, think cadence; if it asks where a specific dissonant note goes, think resolution.

Key things to remember about Resolution

  • Resolution means a dissonant tone or chord moves to a consonant one, releasing musical tension.

  • The leading tone resolves up by half step to tonic, and this is required in outer voices in common-practice part writing.

  • The chordal seventh always resolves down by step, which is the single most useful rule for writing V7 to I correctly.

  • Suspensions resolve down by step while retardations resolve up, and that direction is the only thing separating the two labels.

  • Cadences feel conclusive because their tendency tones resolve; a perfect authentic cadence is resolution at full strength.

  • On part-writing FRQs, unresolved tendency tones are scored as voice-leading errors, so check your leading tones and sevenths before moving on.

Frequently asked questions about Resolution

What is resolution in AP Music Theory?

Resolution is the movement of a dissonant tone or harmony to a consonant one, creating stability and closure. The AP exam tests it through tendency tones (leading tone up, chordal seventh down) and through non-chord tones like suspensions, which resolve down by step.

Does the leading tone always have to resolve up to tonic?

Mostly yes, but with one common exception. In common-practice voice leading the leading tone must resolve up by half step to tonic when it's in an outer voice (soprano or bass). In an inner voice, it can sometimes leap down to scale degree 5 to complete the chord, a move often called a frustrated leading tone.

How is resolution different from a cadence?

Resolution is any dissonance moving to a consonance, anywhere in the music. A cadence is a phrase-ending harmonic formula, like V to I, that creates a sense of arrival. Cadences depend on resolution, but most resolutions don't form cadences.

What's the difference between how a suspension and a retardation resolve?

Direction. A suspension resolves down by step (like the classic 4-3 suspension), while a retardation resolves up by step (typically 7-8 at a cadence). Both are prepared as consonances, held into a dissonance, then resolved by step.

Which way does the seventh of a chord resolve?

Down by step, always, in 18th-century style. In a G7 to C progression, the F (the chordal seventh) must move down to E. Letting the seventh leap or move up is a standard rubric deduction on the part-writing FRQs.
