Unit 6: Harmony and Voice Leading III: Embellishments, Motives, and Melodic Devices

Nonchord tones (NCTs) and ornamentation: the big picture

In tonal music, you usually think of a moment as being “about” a chord: the harmony at that beat is I, V, ii6, and so on. But real melodies rarely stick to chord tones only. Composers constantly decorate (or “embellish”) the basic chord-to-chord framework with extra notes that create motion, expressive tension, and a more singable melodic shape. Those decorative pitches are called nonchord tones (NCTs): notes that sound while a harmony is in effect but are not members of that chord.

In addition to NCTs (which are primarily about voice leading against an implied harmony), musicians also talk about ornamentation and ornaments: decorative figures that add interest, variety, and complexity to a melody. Many ornaments can be understood as stylized ways of presenting NCT behavior (especially in performance practice).

What nonchord tones are (and what they are not)

A nonchord tone is a melodic pitch that creates a temporary dissonance or non-harmonic color against the current harmony and then moves to a chord tone in a controlled way. The key idea is that NCTs are not random; they follow recognizable voice-leading patterns.

It helps to separate two layers:

• The structural (harmonic) layer: the “real” chord tones that define the harmony and progressions (often emphasized on strong beats).
• The surface (melodic) layer: the moving line you actually hear, which may include NCTs between or around the structural tones.

A common AP-level trap is to label an NCT just because it’s “not in the chord,” without checking whether it truly behaves like an embellishment (approach/resolution) or whether the harmony actually changed. In other words, you must decide: is this note an embellishment over the same chord, or did the chord change to include it?

Why NCTs matter in harmony and voice leading

Nonchord tones sit at the intersection of melody and harmony:

• They explain how melodies connect chord tones smoothly (especially by step).
• They create controlled dissonance that must resolve, a central idea in common-practice voice leading.
• They affect Roman-numeral analysis: you don’t want to invent extra chords just because you see extra notes.
• They show up constantly in AP free-response part writing and in multiple-choice listening where you identify patterns.

How NCTs “work”: three questions to ask

To identify (or write) a nonchord tone accurately, ask:

1) Is it accented or unaccented?

• Accented NCTs occur on a metrically strong position (often the beat).
• Unaccented NCTs occur on weaker parts of the beat (often passing “between” strong-beat tones).

2) How is it approached?

• By step (up or down a second)
• By leap (third or larger)
• By tie (a note is held over into a new harmony)

3) How does it resolve?
Most NCTs resolve by step to a chord tone. The direction and timing of that step helps define the NCT type.

Consonance, dissonance, and controlled resolution

In chorale-like common-practice style, dissonances are regulated rather than forbidden. NCTs typically create dissonance on purpose, then “fix” it by stepwise resolution.

A helpful analogy is that chord tones are the pillars of a building; nonchord tones are the decorative arches and pathways connecting them. You can add decoration, but if the pillars don’t line up correctly, the structure collapses.

Quick comparison table of common NCT categories

Common melodic ornaments you should recognize

These are common embellishments/ornaments that add expressive detail. On AP Music Theory, you may encounter them in repertoire-based questions or as vocabulary; conceptually, many relate to step-neighbor motion and/or accented dissonance.

• Trill: rapid alternation between two adjacent notes. It is indicated by a wavy line above or below the note.
• Turn: a quick sequence of four notes in a conventional order. It is indicated by a small curve with a vertical line through it.
• Mordent: rapid alternation between a note and the note above or below it. It is indicated by a short squiggle line above or below the note.
• Grace notes: quick ornamental notes played before a main note. They are indicated by a small note with a diagonal line through the stem.
• Appoggiatura (as an ornament sign): a type of grace note played on the beat, often taking up about half the value of the main note in some styles. It is indicated by a small note with a line through the stem.
• Acciaccatura: a type of grace note played very quickly just before the main note. It is indicated by a small note with a diagonal line through the stem.

Exam Focus

• Typical question patterns:
  • Identify and label nonchord tones in a short excerpt (sometimes specifying accented vs unaccented).
  • Choose the best Roman-numeral analysis by recognizing that certain notes are embellishments, not chord changes.
  • In part-writing contexts, decide whether a dissonance is acceptable based on its preparation and resolution.
  • Recognize common ornament signs (trill/turn/mordent/grace-note figures) and connect them to neighbor-like or accented dissonance behavior.
• Common mistakes:
  • Calling every “non-chord” pitch a new chord instead of checking whether it resolves like an NCT.
  • Ignoring meter: many NCT types depend on whether the note is accented.
  • Forgetting that resolution is part of the definition; if it doesn’t resolve properly, it may be a different type (or poor voice leading).

Stepwise embellishments: passing tones and neighbor tones

The most common and “melody-friendly” embellishments are stepwise ones. They create smooth, singable lines and are often the easiest to hear once you expect stepwise filling-in or circling around a pitch.

Passing tones

A passing tone (PT) is an NCT that fills in stepwise motion between two chord tones (most characteristically when the chord tones are a third apart).

• Approach: by step
• Leave: by step in the same direction
• Effect: creates smooth melodic lines and helps a melody feel like it is moving forward

Passing tones can be:

• Unaccented passing tones: occur on a weak part of the beat; often used to create a sense of motion and flow.
• Accented passing tones: occur on a strong beat; often used to create a sense of tension and release.
• Chromatic passing tones: use chromatic alteration to intensify tension/dissonance.

Example (C major, harmony stays I): C–D–E, where D is not in the C-major triad and functions as a passing tone.

Accented passing tone example idea: If D lands on beat 1 over I and resolves to E on beat 2, D is an accented passing tone (still stepwise in the same direction).

Neighbor tones

A neighbor tone (NT) embellishes a single chord tone by moving away by step and returning by step to the original chord tone. Neighbor tones create a local tension and release without changing the harmony.

• Upper neighbor tone: step above then back; often heard as tension and dissonance.
• Lower neighbor tone: step below then back; often heard as resolution and stability.

Example (C major, harmony I): E–F–E (F is an upper neighbor to E).

Double neighbor (neighbor group)

A double neighbor (neighbor group) uses both upper and lower neighbors around a chord tone, typically in four notes.

A common pattern around scale degree 1 in C major is C–D–B–C. D is the upper neighbor, B is the lower neighbor, and C is the main chord tone.

Chromatic passing and chromatic neighbor tones

Not all NCTs are diatonic. A chromatic passing tone or chromatic neighbor tone uses a pitch outside the key for expressive intensity.

• In minor keys, chromaticism is especially common due to raised 6 and 7.
• In major keys, chromatic neighbors often appear as expressive inflections.

Example (C major): E–E♭–E is a chromatic lower neighbor.

Common pitfall: Don’t automatically call a chromatic note a modulation. A single altered pitch can simply be an embellishment.

Preparation and resolution (why stepwise NCTs behave)

A key voice-leading idea behind passing and neighbor tones is preparation and resolution: how a nonchord tone is approached and how it resolves. Even when a PT/NT is unaccented and quick, it still needs to connect convincingly to surrounding chord tones.

Incomplete neighbor vs true neighbor

A true neighbor tone is step away, step back to the same pitch. If there is a leap on one side, it is more likely an escape tone or appoggiatura depending on accent and direction.

Exam Focus

• Typical question patterns:
  • Identify passing vs neighbor tones and classify as accented/unaccented.
  • In Roman-numeral analysis, treat stepwise in-between notes as NCTs instead of new harmonies.
  • In part writing, incorporate a passing tone in the soprano while maintaining correct voice-leading.
• Common mistakes:
  • Labeling a note as a passing tone when the surrounding notes are not functioning as a stepwise connection between chord tones (passing tones most often connect chord tones a third apart).
  • Forgetting direction: passing tones continue in the same direction; neighbors reverse direction.
  • Misidentifying an accented passing tone as an appoggiatura just because it’s on a strong beat; verify whether the approach is stepwise or by leap.

Tied-note embellishments: suspensions and retardations

Some of the most expressive dissonances in tonal music come from delay: a note that was consonant becomes dissonant because the harmony changes underneath it, and then it resolves.

The three-step model: preparation, dissonance, resolution

A suspension is an accented NCT created by holding a note over (often with a tie) into a new harmony where it becomes dissonant, then resolving it down by step.

1) Preparation: the note is a chord tone in the first harmony (consonant).
2) Suspension: the pitch is held into the next harmony, where it becomes dissonant (typically on a strong beat).
3) Resolution: the suspended pitch resolves down by step to a chord tone.

The result is a feeling of release and resolution because the dissonance is prepared and then “fixed.”

Suspension labels (4–3, 7–6, 9–8)

Suspensions are named by the interval above the bass: 4–3, 7–6, 9–8, etc. The first number is the dissonant interval at the moment of suspension; the second is the consonant interval after resolution.

• 4–3 suspension: the suspended note is a fourth above the bass and resolves down to a third above the bass. This is one of the most common suspensions in tonal music and often creates a feeling of resolution and closure.

Retardations

A retardation is like a suspension but resolves up by step instead of down. It also creates tension and release, but with upward resolution.

Chains of suspensions

A chain of suspensions is a series of suspensions occurring one after another, creating repeated waves of tension and release. This device is often associated with slow movements of sonatas and other instrumental works, where it can increase emotional intensity.

Rearticulated suspensions

A rearticulated suspension repeats the suspended note before it resolves. The repetition creates a sense of tension and prolongs the resolution.

How to write suspensions correctly in four-part texture

To write (or check) a suspension/retardation:

• The suspended pitch must be prepared as a chord tone in the same voice.
• The dissonance is typically accented.
• The resolution should be stepwise (down for suspensions, up for retardations).
• Re-check for forbidden parallels (for example, parallels created at the moment of resolution).

A very common student error is to treat any tied note as a suspension. A tie alone is not enough: the note must become dissonant against the new harmony and then resolve by step.

Suspensions vs accented non-tied dissonances

If a dissonant note is accented and resolves by step but is not prepared by tie, it is usually not a suspension; it is more likely an appoggiatura.

Exam Focus

• Typical question patterns:
  • Identify suspensions/retardations and label the type (such as 4–3 or 7–6).
  • Spot an incorrect suspension (no preparation, wrong resolution, or parallels at resolution).
  • Incorporate a suspension at a cadence while maintaining correct spacing and resolution.
  • Recognize chains of suspensions and rearticulated suspensions as intensification devices.
• Common mistakes:
  • Writing an unprepared suspension.
  • Resolving a suspension in the wrong direction or by leap.
  • Forgetting to check the intervallic result with the bass, leading to parallels when the suspension resolves.

Leap-based embellishments: appoggiaturas, escape tones, and cambiatas

Not all embellishments are step-to-step. Some expressive decorations involve a leap either into or out of the dissonance, which demands extra care in part writing.

Appoggiaturas

An appoggiatura (as an NCT category) is an accented nonchord tone, typically approached by leap and resolved by step (often in the opposite direction of the leap).

• Usually accented (on the beat)
• Often approached by leap
• Resolved by step to a chord tone

This “leaning” effect is why appoggiaturas can sound dramatic and expressive.

Example idea (C major over I): leap to D on beat 1 (nonchord), then resolve down to C on beat 2.

Dissonant vs consonant appoggiaturas:

• A dissonant appoggiatura clashes with the harmony and can create drama or conflict.
• A consonant appoggiatura does not clash with the harmony and is often used as ornamentation or embellishment. In some contexts, consonant appoggiaturas are discussed as “grace-note-like” decorations because they add a graceful touch.

Escape tones (upper and lower)

An escape tone (ET) is typically approached by step and left by leap in the opposite direction. It is commonly unaccented.

It is useful to describe escape tones as upper or lower depending on whether the escape tone itself is above or below the preceding chord tone.

• Many escape tones are quick and occur on weak parts of the beat.
• What defines the category is the step into the nonchord tone followed by the leap away.

Example idea: Over a stable harmony, E–F (step up) then leap down to D; if F is not in the harmony, it can function as an escape tone.

Cambiata (changing-tone idea)

A cambiata (often associated with species counterpoint and chorale-like writing) is a recognized melodic figure in which a dissonant nonchord tone is approached by step and left by leap, followed by stepwise motion that completes the figure.

A common cambiata-like pattern to recognize is: step down to a dissonance, leap up a third, then step down again (often called nota cambiata in some traditions). For AP purposes, the key is to recognize it as a standardized, stylistically controlled pattern so you don’t invent a new chord just because there is a dissonant note.

Practical voice-leading cautions with leap-based NCTs

When adding appoggiaturas or escape tones in four-part writing:

• Leaps in upper voices should generally be followed by stepwise motion in the opposite direction.
• Avoid accented leaps that create harsh dissonant intervals against the bass unless they clearly resolve.
• Don’t let an embellishment create unresolved tendency tones (for example, emphasizing scale degree 7 without a convincing resolution to 1).

Exam Focus

• Typical question patterns:
  • Identify an accented dissonance as appoggiatura vs accented passing tone by checking approach (leap vs step).
  • Recognize and label escape tones (including upper vs lower) by their step-then-leap shape.
  • Treat cambiata figures as embellishment patterns rather than extra chord changes.
• Common mistakes:
  • Calling something an appoggiatura without verifying stepwise resolution.
  • Mislabeling an escape tone as a neighbor tone (escape tones do not return to the same pitch).
  • Writing leap-based embellishments that create parallels or leave tendency tones unresolved.

Contextual embellishments: anticipations, pedals, and arpeggiations

Some embellishments are defined less by the exact step/leap shape and more by timing: how a pitch relates to harmony changes over time.

Anticipations

An anticipation is a note that arrives “early.” It is a nonchord tone in the current harmony but becomes a chord tone in the next harmony.

• Usually unaccented
• Often repeats into the next harmony (sometimes literally repeated, sometimes tied)

Example idea (C major, I to V): a voice plays B just before the harmony changes to V. Over I, B is nonchord; over V, it is chordal.

Pedal points

A pedal point (pedal tone) is a sustained or repeated note—most often in the bass—that begins as a chord tone, then becomes a nonchord tone as harmonies change above it, and finally returns to being a chord tone. Pedals create a sense of stability and tension.

Common types:

• Tonic pedal (scale degree 1)
• Dominant pedal (scale degree 5)

Analytically, you do not change every Roman numeral just to make the pedal note fit; the pedal is allowed to be nonharmonic for a while.

Arpeggiations (broken-chord melodic device)

An arpeggiation is melodic motion that outlines a chord by moving among chord tones (often by leap). Many arpeggiations are not NCTs at all because the pitches are chord members; they matter because they create melodic interest without adding dissonance.

Example idea (C major I arpeggiation): C–E–G–E–C.

Neighbor-note chains and melodic flourishes

In real music, you often get strings of embellishments—passing tones plus neighbors plus anticipations—creating a surface much more active than the underlying chord progression. On AP, you are often expected to label representative or structurally important embellishments (especially accented dissonances) rather than naming every single quick note.

Exam Focus

• Typical question patterns:
  • Identify anticipations at cadences.
  • Recognize a pedal point and analyze the harmonies above it without forcing the pedal to fit.
  • Distinguish arpeggiations (chord tones) from NCTs during melodic/harmonic analysis.
• Common mistakes:
  • Calling an anticipation a passing tone just because it moves by step; check whether it belongs to the next chord.
  • Mis-analyzing pedal passages by changing Roman numerals to accommodate the pedal pitch.
  • Treating arpeggiated chord tones as NCTs.

Embellishing harmonic progressions in four-part writing

Unit 6 is not just naming decorations; it’s understanding how embellishments interact with the harmonic framework and with voice-leading rules.

Skeletal progression vs embellished surface

A practical approach is to reduce a texture to a “skeleton”:

1) Circle the structural chord tones (often on strong beats).
2) Identify the chords (Roman numerals) those structural tones support.
3) Explain in-between notes as NCTs connecting the structure.

When writing, do the same in reverse: write a correct progression first, then add embellishments that don’t break it.

Tonic expansion through embellishment

A common use of embellishment is tonic expansion: prolonging I (or i) using NCTs and melodic patterns so the music doesn’t feel harmonically stuck.

Example idea: keep I for a full measure while soprano moves C–D–E–F–E–D–C. Many notes are embellishments even though the harmony is stable.

Embellishing cadences without ruining them

Cadences (PAC, IAC, HC, etc.) are structural points; embellishments often intensify them:

• Suspensions over V (or over final I) resolving clearly
• Accented NCTs in soprano resolving to scale degree 1 at a PAC
• Anticipations just before the final chord tone

The cadence must still “read” clearly; too many accented dissonances or obscured leading-tone resolution weakens it.

Writing passing/neighbor tones effectively (and not overusing them)

Passing tones and neighbor tones are excellent tools to create interest and variety, but they can become predictable if overused. Good practice includes:

• Consider the harmonic context and ensure the embellished tones make sense over the chord.
• Experiment with rhythms and note durations to create different expressive effects.
• Keep the melodic line singable; don’t add motion just to add motion.

A safe method for adding NCTs in chorale style

1) Write the basic progression with chord tones on main beats.
2) Choose one voice to embellish (often soprano).
3) Add unaccented passing tones first.
4) Add neighbors or suspensions if they resolve correctly.
5) Re-check the whole texture for:

• Parallel 5ths/8ves created by embellishing motion
• Hidden/direct 5ths/8ves (especially soprano with bass)
• Doubling issues that appear if you accidentally implied a new harmony
• Unresolved tendency tones

Worked mini-example (conceptual)

Harmony: I moving to V in C major, soprano structural tones E (over I) to D (over V).

• Skeleton soprano: E → D
• Possible embellishment: E–F–E–D (F is an upper neighbor to E)

Over I (C–E–G), F is dissonant, but if it’s unaccented and resolves correctly, it’s acceptable. The harmony did not need to become “IV” just because F appeared.

Harmonic rhythm and “too many chords”

Harmonic rhythm is how often chords change. A major beginner error is assuming every note implies a new chord, creating implausibly fast harmonic rhythm. If the main beats support a coherent progression, treat many in-between notes as embellishments.

Exam Focus

• Typical question patterns:
  • Choose an analysis with the correct harmonic rhythm by recognizing embellishments.
  • In part-writing, add or identify a passing tone/suspension while keeping correct voice leading.
  • Spot voice-leading errors caused by embellishments (especially parallels created at resolution).
• Common mistakes:
  • Over-chordifying: inventing a new Roman numeral for every melodic pitch.
  • Adding an embellished soprano line without checking for parallels with the bass.
  • Weakening cadences by obscuring leading-tone resolution or placing unstable tones on the strongest beats without proper handling.

Motives and motivic transformations

Harmony gives music structure, but motives give it identity: small melodic and/or rhythmic cells that recur and help a passage feel unified.

What a motive is

A motive (motif) is a short, recognizable musical idea—often just a few notes—and is often described as the smallest identifiable musical idea that can generate larger structure.

A motive can be defined by:

• Rhythm
• Contour
• Intervals
• Scale-degree pattern (for example, 5–6–5–3)

Why motives matter

Motives help listeners recognize patterns, help performers predict what comes next (including in sight singing), and often interact with harmony (for example, consistently landing on certain chord tones or prolonging a harmony through repetition).

How to identify a motive (practical method)

1) Look for exact repetition.
2) Look for near repetition (same rhythm but different pitches, or same contour starting on a different scale degree).
3) Decide what is essential: rhythm, intervals, or both.
4) Mark motive boundaries (often 2–5 notes).

A common mistake is labeling an entire phrase as a motive; phrases contain motives, but motives are typically smaller and reusable.

Motivic transformation

Motivic transformation is altering a motive to create a related idea. Common transformations include:

• Sequence / transposition: repeating the motive at a new pitch level.
• Transposed motives: the same motive in a different key or pitch level.
  • Exact transposed motives: intervals are preserved exactly.
  • Chromatic transposed motives: some intervals are altered chromatically.
• Inversion: the motive is “upside down” (interval directions reversed).
• Retrograde: the motive is played backward.
• Augmentation: longer note values (slower rhythmic presentation).
• Diminution: shorter note values (faster rhythmic presentation).
• Fragmentation / fragmented motive: breaking the motive into smaller pieces.
• Truncation / truncated motive: shortening a motive by removing some notes.
• Extension / extended motive: repeating/continuing the motive beyond its original length.

Motives and embellishments interact

Motives often include embellishing tones (for example, a neighbor figure) repeated in different harmonic contexts. That means many notes can occur over one harmony due to motivic surface activity.

Exam Focus

• Typical question patterns:
  • Identify a motive and recognize a varied repetition (same rhythm, transposed pitches).
  • In listening, notice when a pattern returns and use that to answer structure questions.
  • Connect motivic repetition to phrase structure.
• Common mistakes:
  • Defining a motive too broadly (an entire phrase), making it impossible to track.
  • Ignoring rhythm; many motives are primarily rhythmic.
  • Confusing systematic sequence/transposition with random repetition.

Melodic devices and sequences (melodic and harmonic)

Beyond single NCT labels and small motives, Unit 6 includes phrase-level tools: sequences, repetition types, and common patterned progressions.

Melodic sequence and repetition types

A sequence is the repetition of a musical idea at a different pitch level. Sequences can be short or long patterns and often create tension and release by extending a phrase.

How to spot a sequence:

• Intervals repeat in the same order.
• Rhythm is often identical.
• The pattern restarts on a new pitch level.

Types:

• Melodic sequences: the melody repeats higher or lower.
• Harmonic sequences: the harmony also follows a pattern.
• Ascending sequence: pattern moves upward, often creating excitement and anticipation.
• Descending sequence: pattern moves downward, often creating relaxation and resolution.
• Diatonic melodic sequences: stay within one key, often creating stability and familiarity.
• Chromatic melodic sequences: include chromatic notes (up to all 12 tones), often creating tension and dissonance.

Not all repetition is a sequence:

• Exact repetition: same pitches and rhythm.
• Varied repetition: similar rhythm/contour with small pitch adjustments to fit harmony.

Conjunct vs disjunct motion (melodic fluency)

A well-formed melody balances:

• Conjunct motion (stepwise) for singability
• Disjunct motion (leaps) for energy and shape

A common melodic habit (and helpful compositional/singing strategy) is: after a leap, recover by stepwise motion in the opposite direction.

Contour, range, and climax

• Contour: overall up/down shape.
• Range: distance between lowest and highest pitch.
• Climax: the high point, often aligned with harmonic intensity (such as approaching a cadence).

“Filling in” vs “circling” devices

You can often describe melodic surfaces by two big behaviors:

• Filling in: passing motion and sequential extension.
• Circling: neighbor figures/turn-like motion around a pitch.

Functions of melodic sequences

Melodic sequences commonly:

• Create unity and coherence
• Provide tension and release
• Create excitement and anticipation
• Create relaxation and resolution
• Add complexity and interest

Harmonic sequences and patterned progressions

A harmonic sequence is a series of chords that follows a consistent intervallic pattern.

Directional types:

• Descending harmonic sequences: chords move down by a consistent interval; often associated with sad or melancholic affect.
• Ascending harmonic sequences: chords move up by a consistent interval; often associated with uplifting or triumphant affect.

Some harmonic progressions are described (by contour/function) as:

• Monte: chords move upward, creating tension and anticipation.
• Fonte: chords move downward, creating release and relaxation.
• Ponte: chords meander (neither clearly up nor down), creating ambiguity and unpredictability.

A memory aid embedded in these terms: Monte creates tension, fonte creates release, and ponte creates ambiguity.

Texture-based sequence descriptions

• Full texture sequence: all voices move in the same rhythm and direction.
• Linear intervallic pattern sequence: the intervals within each voice follow a pattern.

Common interval-based sequential motions

• Descending fifths progression: chords move down by fifth.
• Ascending fifths sequence: chords move up by fifth.
• Descending thirds sequence: chords move down by third.
• Ascending seconds sequence: chords move up by second.

Ascending parallel 6/5 chords

Ascending parallel 6/5 chords are a common classical progression type featuring successive chords that each include 6th and 5th intervals above the bass (as a sonority description). They can be major or minor depending on key/context, are often found in the middle or end of a musical phrase, and can help lead into a cadence or resolution.

Pachelbel sequence

A Pachelbel sequence uses the chord pattern:

I, V, vi, iii, IV, I, IV, V

These sequences feature a repeating pattern of chords that are played in a specific order.

Structure description:

• First chord progression: establishes the key and sets the tone.
• Second chord progression: variation of the first, typically with a change in melody or harmony.
• Final chord progression: resolves the sequence and brings it to a close.

Minuets and ternary form (ABA)

A minuet is commonly associated with a three-part musical form represented as ABA (ternary form).

• The A section is usually the main theme of the piece and returns at the end.
• The B section is usually in a contrasting key, tempo, or melody, providing contrast.

A simple outline:

• A (theme 1)
• B (contrasting theme)
• A (theme 1 repeated)

Exam Focus

• Typical question patterns:
  • Identify a sequence (aurally or visually) and describe what repeats.
  • Distinguish exact repetition, varied repetition, and true sequence (transposition to a new pitch level).
  • Recognize diatonic vs chromatic sequences and connect them to increased tension.
  • Identify common sequential harmonic motions (descending fifths, etc.) and patterned progressions like the Pachelbel sequence.
  • Recognize ternary (ABA) form in minuet-like excerpts and relate motives/sequences to the A and B sections.
• Common mistakes:
  • Assuming any repetition is a sequence; a sequence specifically involves transposition.
  • Missing sequences that are rhythmically identical but adjusted to stay diatonic.
  • Describing contour too vaguely (“it goes up”) instead of naming the repeating unit or pattern.

Applying Unit 6 skills: analysis, dictation, and sight singing

These concepts are tools for the main AP skill areas: harmonic analysis, melodic dictation, and sight singing.

Aural recognition of embellishments

Listening cues:

• Unaccented passing/neighbor tones often sound like brief connective motion; the harmony doesn’t feel like it changed.
• Suspensions sound like a stressed dissonance that “hangs” and then releases.
• Appoggiaturas sound like a strong-beat lean that resolves by step.
• Anticipations sound like a note that belongs to what comes next and is often repeated.

A major listening breakthrough is focusing on stable tones (often on beats) and treating many in-between notes as motion rather than new harmony.

Dictation: use structure instead of guessing

A reliable approach:

1) Identify key and meter.
2) Listen for cadential scale-degree patterns.
3) Write strong-beat tones first (more likely chord tones).
4) Fill in weak-beat notes as passing/neighbor motion.
5) Check for notes held across chord changes (possible suspensions/retardations) or notes arriving early (anticipations).

This reduces the tendency to overcomplicate a melody with imagined leaps or unnecessary accidentals.

Sight singing: motives and patterns as your roadmap

Motives and sequences make melodies predictable:

• If you identify a motive in measure 1, look for it again, possibly transposed.
• If you see stepwise motion between chord tones, anticipate passing tones.
• If you see a tied note across a barline, be alert for suspension-like behavior (even if accompaniment isn’t present).

Steady pulse and accurate contour are always priorities; pattern recognition helps you keep flow even when intervals look intimidating.

Analysis writing: what to label vs what to leave implicit

In short AP analyses:

• Label structurally important NCTs (especially accented dissonances like suspensions and appoggiaturas).
• Keep Roman numerals sensible by recognizing embellishments and harmonic rhythm.
• When asked about melodic devices, point to a clear motive or sequence and describe the transformation (transposed, inverted, augmented, diminished, fragmented, etc.).

Common integrated trap situations

• Accented passing tone vs appoggiatura: both can be accented and resolve by step; check whether the approach was step (passing) or leap (appoggiatura).
• Anticipation vs suspension: anticipation arrives early and belongs to the next chord; suspension is held over from the previous harmony and resolves after the dissonance.
• Pedal point and harmonic analysis: don’t force chords to fit the pedal; analyze harmonies above.
• Sequences and harmony: sometimes melodic sequences ride over real harmonic sequences; other times they are mostly surface decoration. Look to bass/root motion and strong beats.

Exam Focus

• Typical question patterns:
  • In dictation, identify embellishing notes so the melody fits the key and meter.
  • In listening MC, distinguish harmonic change from embellishment over the same harmony.
  • In sight singing, perform sequences and stepwise embellishments accurately by recognizing repeating patterns.
  • In written analysis, justify a slower harmonic rhythm by labeling NCTs instead of adding chords.
• Common mistakes:
  • Writing too many leaps in dictation because embellishments are mistaken for structural tones.
  • Misreading ties as automatically indicating suspensions without considering harmony and resolution.
  • Over-labeling: trying to name every note rather than prioritizing structurally significant embellishments and patterns.
