Cadence

In music, a cadence is a of at least two chords that concludes a musical or section, creating a sense of , rest, or partial closure through means. The term originates from the Latin cadere, meaning "to fall," which historically alluded to the descending stepwise motion in the or bass line at the end of phrases in early polyphonic . Cadences serve as essential structural elements in Western tonal music, functioning analogously to in by articulating the boundaries of and larger forms, thereby guiding the listener's perception of musical flow and hierarchy. They emerged prominently in the development of during the , evolving from practices to support the establishment of in the common practice era. The four main types—perfect (V–I), plagal (IV–I), half (ending on V), and deceptive (V–vi)—each convey varying degrees of finality or surprise, influencing everything from simple folk tunes to complex symphonic works. Beyond classical contexts, cadences appear in diverse genres, including , pop, and even non-Western traditions adapted through global influences, underscoring their versatility in creating rhythmic and emotional .

Fundamentals

Definition and Role

In music theory, a cadence is a melodic or formula that creates a of , pause, or conclusion, typically marking the end of a or larger . This concept, rooted in tonal practices, functions as a point of arrival, fulfilling listener expectations built through preceding musical tension. The primary roles of cadences include providing closure to musical phrases, sections, or entire pieces, thereby articulating the overall form and allowing the listener to perceive structural boundaries. They also establish and reinforce tonal centers by directing harmonic motion toward stability, often the tonic, which anchors the key of the composition. Furthermore, cadences contribute to formal structures, such as binary form—where they delineate the two main parts—or sonata form, where they serve as signposts for thematic divisions and recapitulations. Cadences are primarily , relying on progressions to generate and resolve , though they may incorporate melodic or rhythmic patterns to enhance effects of or forward . In both cases, they signal whether the music should pause for completion or proceed with continuation, shaping the perceptual flow of the piece. For instance, in simple tonal music, a basic cadence might conclude a by landing on the , offering a momentary that invites before the next idea begins. Common classifications, such as the authentic cadence, exemplify full resolution to the , underscoring these functional principles.

Nomenclature and Terminology

The term "cadence" derives from the Latin cadentia, meaning "a falling," and evolved from the medieval concept of the clausula vera ("true close"), a dyadic intervallic formula providing closure in polyphonic of the 12th to 16th centuries. This clausula vera, typically involving a sixth resolving to an between voices, served as the structural basis for later cadences in tonal , transitioning from modal to functional during the . By the , theorists including Johannes Lippius contributed to the development of theory, including descriptions of cadences as progressions ending phrases and marking a shift from intervallic to chordal resolution. In English-language , cadences are classified as authentic, plagal, half, and deceptive, with subtypes like and imperfect authentic cadence (IAC). Equivalent terms appear in other languages: in , cadence parfaite for perfect cadence and cadence imparfaite for imperfect; in , authentische Kadenz and perfekte Kadenz; in , cadenza autentica and cadenza perfetta; and in , cadencia auténtica and cadencia perfecta. These variations reflect national traditions in , with and terms emphasizing perfection or authenticity, while retains roots in earlier contrapuntal . Common abbreviations in modern include PAC for perfect authentic cadence (V–I with both chords in root position and soprano resolving to ), IAC for imperfect authentic cadence (V–I with variations in voicing or inversion), HC for half cadence (ending on V), PC for plagal cadence (IV–I), and for deceptive cadence (V–vi). These symbols facilitate analysis in scores and textbooks, standardizing discussion across English-dominant academic contexts. Beyond traditions, analogous concepts of phrase closure exist in non- music, though not always . In , sam denotes the first beat of a tala (rhythmic cycle), providing rhythmic and marking the return to , paralleling the conclusive function of a cadence. Similarly, in , watad (a metrical "peg" from prosody) structures rhythmic units in iqa'at, contributing to cadential emphasis at phrase ends akin to .

Primary Harmonic Classifications

Authentic Cadence

The authentic cadence, also known as the full cadence, is a harmonic progression from the dominant (V) to the (I) that provides the strongest of and in tonal . This V–I motion establishes the as the gravitational center, marking the end of a , , or entire piece with a conclusive effect. Unlike weaker progressions such as the half cadence, which ends on the dominant for a of continuation, the authentic cadence achieves full stability on the . Authentic cadences are classified into two main subtypes: the perfect authentic cadence () and the imperfect authentic cadence (IAC). A perfect authentic cadence requires both the dominant and chords to be in position, with the moving from the dominant's (scale 5) to the 's ( 1), and the (typically the voice) concluding on the ( 1) above the . This configuration maximizes the sense of finality through precise alignment of structural elements. In contrast, an imperfect authentic cadence follows the same V–I progression but relaxes at least one of these criteria: the chords may be inverted, the may not end on the , or the may conclude on the third ( 3) or fifth ( 5) of the rather than the . These variations still convey resolution but with slightly less emphasis than the . Key harmonic details emphasize root-position triads for both to ensure stability and strength, with the dominant often appearing as a V7 to heighten tension before release. rules are crucial for smooth : the (scale degree 7 in the dominant ) must resolve upward by step to the (scale degree 1), typically in an outer voice for prominence, while the dominant's third (scale degree 7 as the chord seventh in V7) resolves downward by step to the 's third. These resolutions create stepwise motion and avoid parallels, reinforcing the cadence's structural integrity. A basic example occurs in C major, where the dominant chord is G7 (G–B–D–F), progressing to the tonic C major (C–E–G–C). For a perfect authentic cadence, the bass moves from G to C, the soprano from B () to C, the alto from F (seventh) to E, and the tenor from D to G, as shown in simple four-part notation:
  B     C
  F     E
  D     G
  G     C
G7     C
This progression illustrates the classic , with the B ascending to C and the seventh F descending to E. An imperfect variant might place the on E (the third) over the final C , reducing the emphatic arrival on the .

Plagal Cadence

The plagal cadence consists of a progression from the (IV in major keys or iv in keys) to the (I or i), providing a sense of that is gentler than other cadential types due to its stepwise motion. This structure, often notated as IV–I in major or iv–i in , features smoother , with the descending a (or ascending a fifth) while upper voices typically move by step or remain stationary, minimizing dissonance and creating a serene . It is frequently employed in hymns and chorales for its calming effect, earning the nickname "Amen cadence" from its common use in setting the word "Amen" at the end of sacred pieces. Subtypes of the plagal cadence include the standard form in major keys (IV–I), which reinforces tonal stability, and the minor plagal (iv–i), prevalent in minor-key contexts for a subdued resolution, as seen in works like Mendelssohn's Reformation Symphony. Another variant is the Moravian cadence, a folk-influenced modification associated with Czech composers such as and , where the outer voices of the chord resolve inward by a whole step to the , incorporating modal inflections for a distinctive ethnic flavor. In notation, a standard plagal in might progress from (IV: F–A–C) to (I: C–E–G), while in , it could move from (iv: D–F–A) to (i: A–C–E). Often following an authentic cadence in sequences, the plagal provides additional reinforcement to the arrival, enhancing finality without the sharper tension of dominant preparation. For instance, the "Amen" progression appears in countless hymnals, such as the concluding –I in the , underscoring its role in .

Half Cadence

The half cadence, also known as an or semicadence, is a progression that concludes on the (V), producing an incomplete and a of ongoing tension rather than closure. This cadence typically involves a from any preceding to V, most commonly from the (I to V) or (ii to V), marking the midpoint of a and signaling . By suspending on the unstable dominant, it heightens anticipation, often propelling the music forward to subsequent phrases. Several subtypes of the half cadence exist, distinguished by their chordal approaches and implications. The standard half cadence relies on diatonic progressions like I–V or –V in major keys, emphasizing functional within the prevailing . In keys, the Phrygian half cadence employs a first-inversion (iv⁶) resolving to , featuring a characteristic half-step ascent in the bass from the lowered fourth scale degree to the dominant , which evokes a flavor reminiscent of the . The Lydian half cadence variant, less common but notable in contexts, incorporates a raised fourth scale degree (#iv⁶ to ) in , introducing an augmented second that lends a brighter, more elevated . Early subtypes include the Burgundian cadence (IV–), prevalent in 14th- and 15th-century music, where the directly precedes the dominant without inversion, creating a straightforward yet tense progression in nascent tonal practices. Additionally, the plagal half cadence (IV–) derives from function, offering a milder compared to predominant approaches but still avoiding . Harmonically, all half cadences prioritize the dominant's inherent instability—its between the third and seventh in root position—to sustain harmonic momentum, making them ideal for phrase-internal divisions. They frequently appear at structural midpoints, such as the end of antecedent phrases in forms or the first section of structures, where an I–V progression in the establishes temporary repose before or repetition. For instance, in 18th-century forms, a half cadence often closes the initial section on V, fostering continuity into the dominant . In minor-key works, the Phrygian half cadence enhances expressive depth, as seen in chorales where iv⁶–V punctuates emotional transitions. This cadence type thus serves as a pivotal tool for continuation, often leading into an authentic cadence for eventual .

Deceptive Cadence

The deceptive cadence, also referred to as the interrupted cadence, arises when a dominant-functioning (V or V⁷) resolves not to the (I) but to the ( in keys or VI in keys), thereby evading the expected harmonic closure and introducing an element of surprise. This progression creates a momentary of due to the shared tones between V and vi/VI, particularly the common tone between the root of V and the fifth of vi/VI, but ultimately prolongs tension by landing on a chord that implies further continuation rather than finality. In , the bass typically ascends stepwise from the dominant's root (scale degree 5) to the submediant's root (scale degree 6), while the (scale degree 7) in the dominant often descends to the submediant's third (scale degree 6 of the key, which is the third of vi); for instance, in C , a V (G-B-D) might lead to vi (A-C-E) with the moving from B to C and the from D to E. This cadence's primary effect is emotional surprise, as it subverts the strong pull of the dominant toward the tonic, fostering a sense of evasion that heightens expressiveness and sustains listener interest, often in mid-phrase positions where closure is anticipated. Unlike the authentic cadence's straightforward resolution, the deceptive variant delays fulfillment, allowing composers to extend phrases or build suspense before eventual tonic arrival. Variations of the deceptive cadence extend beyond V-vi/VI to other non-tonic resolutions, such as V to bVI (the lowered submediant), which incorporates modal mixture for added color and is particularly effective in minor keys or transitional passages. These are commonly found in the development sections of classical sonata forms, where they contribute to thematic instability and dramatic prolongation. A representative example occurs in Beethoven's Piano Sonata No. 8 in C minor, Op. 13 ("Pathétique"), where V-vi progressions in the development section underscore motifs of unrest, with voice leading emphasizing the bass ascent and leading-tone descent to amplify the deceptive twist.

Specialized and Variant Cadences

Phrygian and Lydian Variants

The Phrygian half cadence represents a modal-inflected variant of the half cadence, occurring exclusively in minor keys through the progression iv⁶ to . This structure features a minor iv chord in first inversion resolving to the root-position dominant , with the bass line descending by half step from the sixth scale degree (♭⁶) to the fifth (⁵), mirroring the characteristic half-step approach between the second and first degrees of the . This provides a sense of unresolved expectancy infused with modal color. Derived from Renaissance modal theory, the Phrygian half cadence employs borrowing from the parallel Phrygian mode to evoke an exotic, introspective quality, often appearing in polyphonic works and later adaptations. For instance, in A minor, the progression might involve F-A-D (iv⁶) to E-G♯-B (V). The Lydian variant introduces a brighter tension to the half cadence by raising the fourth scale degree in the pre-dominant chord, typically forming #iv⁶ to V in minor keys. This alteration raises the iv chord by a half step, creating an augmented second interval in the bass or voice leading that borrows from Lydian modal characteristics for heightened color and instability before resolving to V. Unlike the descending half step of the Phrygian type, the Lydian approach often involves a whole-step bass motion approached from below, lending a more expansive, luminous quality to the progression. For example, in A minor, this might involve F♯-A♯-D♯ (raised iv⁶, bass A♯) to E-G♯-B (V). The Lydian cadence appears in modern folk contexts, enhancing modal ambiguity, such as in or traditions adapting major-key inflections to minor frameworks for brighter harmonic shifts.

Inverted and Upper Leading-Tone Cadences

Inverted cadences involve the use of inverted , particularly the dominant in first inversion (V⁶/₅), leading to the (I), which results in a weaker sense of resolution compared to root-position cadences due to the less stable note. This inversion places the third of the dominant in the , altering the typical strong pull of the root-position dominant by reducing the intervallic tension in the bass line. in these cadences requires careful adjustment to maintain smooth connections, often resolving the upward to the while the third of V moves to the root of I, creating a stepwise motion that prioritizes melodic flow over harmonic force. Such inverted dominant cadences are employed to facilitate smoother bass lines, particularly in Baroque continuo practice, where the figured bass notation allows for inversions to avoid large leaps and support continuous melodic progression in accompanying parts. For instance, in J.S. Bach's chorales and suites, inverted V⁶/₅ to I appears in phrase endings to connect sections fluidly without abrupt bass shifts. The upper leading-tone cadence, prevalent in minor keys, incorporates the raised sixth scale degree (from the melodic minor) within the dominant chord or preceding harmonies to heighten tension and enhance resolution. This raised sixth functions as an upper leading tone, resolving downward by step to the fifth of the tonic, while avoiding the augmented second interval that arises between the natural sixth and raised seventh in harmonic minor. In voice leading, it allows for parallel sixths or contrary motion between inner voices, adding chromatic color and intensifying the approach to the tonic without disrupting the overall cadence structure. In Romantic miniatures, such as those by Chopin, the upper variant appears in subtle cadential figures to evoke emotional depth, often in the inner voices of a V-I progression in minor, where the raised sixth introduces a momentary inflection for expressive tension. This technique builds on authentic cadence frameworks but modifies the dominant's upper structure for nuanced harmonic shading.

Picardy Third

The , also known as the tierce de Picardie, is a harmonic resolution in which a or in key ends with a major , substituting a major third for the expected above the root to produce an unanticipated sense of brightness and closure. This device, borrowed from the parallel major mode, imparts an uplifting or hopeful effect to otherwise melancholic minor-key music, often evoking emotional contrast at the conclusion. The term originates from the Picardy region in northern , where the technique was especially prevalent in Renaissance-era , though the precise etymology remains uncertain. Historically, the Picardy third emerged around 1500 as composers began incorporating thirds into final sonorities, gaining widespread adoption in the second half of the during the . By the late Renaissance, in the masses of , major triads accounted for approximately 85% of final chords, reflecting its normative status in sacred . The practice persisted prominently into the period, where it appeared frequently in chorales, suites, and fugues, before declining in later eras though still occasionally employed. In terms of harmonic structure, the Picardy third typically manifests as a to a i (e.g., from v-i or V-i in a context), or in a plagal form as IV-i with the final i , most commonly at the end of entire pieces or individual movements to maximize its surprising affective impact. It functions as a mixture, drawing the from the parallel major key while retaining the minor-key framework elsewhere. Representative examples include J.S. Bach's French Suite No. 1 in , BWV 812, where the concludes on a major after establishing the . Similarly, Bach's Fugue No. 2 in C from , BWV 847, employs a in its final measures to provide a brighter . In repertoire, Palestrina's motets and masses routinely feature this ending, as seen in his , underscoring its role in creating a sense of divine affirmation.

Rhythmic Aspects

Rhythmic Cadence

A rhythmic cadence is a melodic or gesture characterized by specific temporal patterns that signal the conclusion of a musical , operating independently of structure to provide a of through alone. These patterns typically involve a deviation from the established , followed by a that emphasizes stability, such as a return to the metric framework or a momentary of motion. In essence, it functions as the rhythmic equivalent of in , marking pauses or arrivals without reliance on relationships. Key structures of rhythmic cadences include s, which extend a beyond its notated duration to create an expressive hold; s that introduce for dramatic effect; and patterns that shift emphasis to off-beats before aligning with the , fostering and release. For instance, a over the final of a melodic line allows the performer to linger, heightening the of finality, while a following a series of active rhythms provides a clear temporal break. -based patterns often feature agogic stresses on weaker s resolving to stronger ones, as seen in repeated short-long rhythmic motifs that culminate in a sustained . Examples of rhythmic cadences appear across musical domains, such as in percussion ensembles where patterns build syncopated complexity before resolving into a unified on the , signaling phrase ends in marching or ritual music. In melodic lines, a common instance is the elongation of the final in vocal phrases, mirroring natural speech inflections for . The traces parallels to , where rhythmic feet derived from poetic meters—such as dactylic or iambic patterns—structured song phrases with temporal resolutions akin to modern cadences, emphasizing long-short durations for emphatic endings. In contemporary , these manifest in pop hooks, like the rhythmic tag in a that repeats a syncopated figure before a held note or , enhancing memorability through pure temporal design. Unlike cadences, which resolve through chordal tension, rhythmic cadences achieve their effect primarily via timing, though they may complement harmonic arrivals in fuller textures.

Rhythmic Classifications in Harmony

In harmonic cadences, rhythmic position plays a crucial role in determining the sense of resolution, with classifications distinguishing between based on strength. A masculine cadence resolves on a strong , typically the , providing a direct and emphatic closure to the . In contrast, a feminine cadence resolves on a weak , often following an of the final on the strong , which creates a more extended and less abrupt sense of arrival. These rhythmic distinctions apply to various harmonic progressions, such as the authentic V-I, enhancing the cadence's expressive impact without altering the underlying al structure. Rhythmic variations further modify harmonic cadences through techniques like and , which delay or overlap resolutions to heighten tension. A suspended cadence incorporates a —typically a dissonant non-chord tone held over from the previous —delaying the resolution of the dominant to , as seen in compound cadences where a 4-3 (do to ) occurs over the dominant's . This creates a poignant delay in the expected V-I progression, emphasizing the dissonance before stepwise downward. , meanwhile, achieve overlap by starting the next simultaneously with the final of the current one, effectively shortening the phrase while maintaining forward momentum and avoiding a full pause. Hemiola introduces rhythmic complexity to cadential approaches, superimposing a ratio that temporarily shifts the perceived meter, often aligning with the to propel toward . In cadential contexts, this rhythmic device groups three pulses in the time of two, creating a sense of acceleration or cross-accentuation that integrates with the V-I progression, as exemplified in Handel's works where the second supports the bass's cadential motion. Such integration can involve syncopated entrances of chord tones, where off-beat arrivals of the dominant or heighten the rhythmic drive without disrupting the framework. Illustrative examples abound in Baroque and Classical repertoire. In Arcangelo Corelli's trio , suspensions frequently embellish cadences, such as 7-6 or 4-3 figures over the dominant, adding expressive delay to the in works like Op. 3 No. 11. Classical composers employed rhythmic evasion—subtly altering the expected metric placement of the final —to evade full closure, as in evaded authentic cadences where the shifts to a weak beat or overlaps with new material, contributing to phrase extension in forms.

Historical Contexts

Medieval and Renaissance Polyphony

In medieval and Renaissance , cadences served as essential points of resolution within contrapuntal textures, emphasizing frameworks and imperfect consonances rather than the major-minor of later periods. The clausula vera, or true cadence, emerged as the foundational type, characterized by contrary stepwise motion between two voices resolving to a or on the mode's final. This progression provided structural closure at phrase ends and was ubiquitous in polyphonic compositions, evolving from the simpler parallel of earlier centuries where voices moved in parallel intervals to more directed contrary motion for stability. Specific cadence variants adapted to modal polyphony included the plagal form, which resolved from the mode's subfinal or dominant to the final, often reinforcing the plagal modes (hypomodes) through bass motion by fourth or fifth. The rest or cadence introduced a brief silence or pause after an imperfect interval, marking a rhetorical break without full resolution, while the evaded cadence avoided direct resolution by having one voice leap away from the expected consonance, typically to evade parallel motion or imperfect intervals like the third or sixth. The cadence, named after the Italian composer , featured an unstable in the expanding outward to an , often with an escape tone in the upper voice narrowing briefly to a fifth before resolving, adding melodic fluency to ballate. Similarly, the English cadence, prominent in works by composers like , involved a contrapuntal pattern featuring a between the flattened and natural leading tones in an inner voice, creating dissonance and highlighting modal ambiguities. Harmonically, these cadences prioritized resolutions, such as leading tones resolving to in authentic modes or intervals like the persisting before perfect consonances, fostering a sense of directed flow without strong dominant-tonic polarity. In Guillaume de Machaut's (c. 1364), double leading-tone approaches to the clausula vera appear in the and , illustrating late medieval integration of with cadential punctuation. Guillaume Dufay's masses, such as Missa Se la face ay pale (c. 1450), employed evaded cadences in the to articulate sections, blending and English influences while evolving toward fuller polyphonic closure. These practices laid contrapuntal groundwork that prefigured the tonal authentic cadence of the common practice era.

Common Practice Period

During the (c. 1600–1900), encompassing the , Classical, and eras, cadences became standardized as fundamental harmonic progressions that articulated phrase structure, sectional divisions, and overall tonal coherence in Western art music. Authentic cadences (V–I) and half cadences (ending on V) functioned as primary structural pillars, providing resolution and tension, respectively, in forms such as and fugues. These build on the core classifications of cadential types while adapting to the era's evolving stylistic demands. In , prevalent in the Classical and Romantic periods, half cadences typically marked the conclusion of the transition section in the exposition, creating instability before the secondary theme, as seen in Haydn's in , Op. 9 No. 4, where a half cadence in the dominant key heightens anticipation. Authentic cadences, conversely, resolved major sections like the recapitulation, ensuring tonal return; Wolfgang Amadeus Mozart's Piano Sonata in C major, K. 545, exemplifies this with a perfect authentic cadence ( resolving to over I) at the movement's close. In fugues, such as those by Johann , authentic cadences delineated episodes and reinforced the , while half cadences facilitated modulatory episodes, structuring the contrapuntal unfolding. Plagal cadences (IV–I), often termed the "Amen" cadence, appeared frequently in chorales and arias for a sense of gentle closure, notably in Bach's harmonizations where they concluded verses, evoking liturgical finality without the intensity of V–I. Deceptive cadences (V–vi) served to evade for dramatic surprise or to pivot toward new keys during modulations, as in Mozart's "Voi che sapete" from , where a deceptive resolution heightens emotional tension before reaffirming the . Period-specific emphases further distinguished cadential practices: Baroque composers like Bach prioritized the perfect authentic cadence for emphatic closure, reflecting the era's drive toward tonal polarity. The Classical period, exemplified by Haydn and , achieved balance through varied cadential phrasing—half cadences for open-ended phrases and authentic for conclusive ones—in developments that explored tonal contrast without excess. In the Romantic era, cadences underwent extensions via prolonged dominants, chromatic insertions, and appoggiaturas, amplifying expressivity; for instance, the "dream cadence" (a dominant resolving unconventionally) in works by composers like delayed resolution for heightened .

Baroque-Specific Variants

In the Baroque era, composers developed nuanced cadence variants that leveraged suspensions and dissonances to heighten emotional tension and resolution within the emerging tonal framework. One such variant is the Corelli cadence, named for (1653–1713), which features the resolution of a (V7) to the (I), where the seventh of the V7 is suspended over the bass and resolves downward to form the major or of the chord. This creates a poignant clash, often involving a 4–3 in an upper voice against the , emphasizing the dissonance before its release. Corelli employed this cadence extensively in his concerti grossi, Op. 6 (published 1714), particularly in slow movements like the of No. 2 in , where it underscores the contrast between concertino and groups for a refined, expressive close. The English cadence, a hallmark of English Baroque polyphony, involves a 4–3 suspension in an inner voice—typically the or —creating a cross-relation between the flattened (^b7) and natural (^#7) scale degrees during the approach to the authentic cadence (V–I). This , resolved stepwise, imparts a distinctive flavor and textural richness, especially in consort music where inner parts weave intricate . (1659–1695) masterfully integrated this variant in his sacred anthems, such as "Rejoice in the Lord alway" (Z. 49, ca. 1687), where the suspended dissonance in the accompaniment enhances the jubilant section, and "My heart is inditing" (Z. 190, 1697), adding poignant dissonance to the choral resolutions. The technique, rooted in earlier English polyphonic traditions, persisted in consorts due to the ensemble's emphasis on balanced, imitative textures. Beyond these, inverted cadences played a key role in Baroque continuo practice, where first-inversion forms of the dominant (V6) or (I6) smoothed bass lines and prevented parallel intervals during realization. This approach allowed for fluid phrase endings in accompanied works, as the inverted V6–I progression maintained continuity without abrupt root-position leaps, common in trio sonatas and keyboard realizations. In ground bass compositions, plagal cadences (IV–I) offered a subdued alternative to authentic closures, varying the over the . Purcell frequently used such progressions in his ground bass anthems, like the verse sections of "Rejoice in the Lord alway," where the IV–I links iterations of the bass pattern, fostering a sense of serene progression amid the repetition.

Genre-Specific Applications

In Jazz

In jazz, the ii-V-I progression serves as a foundational cadence, functioning as an extended form of the authentic cadence through the resolution of a to the . This sequence typically involves a minor chord (often a seventh), followed by a V7 chord, resolving to the , creating tension and release via the dominant's interval. The progression's ubiquity stems from its role in delineating harmonic phrases in standards, allowing improvisers to navigate changes with melodic lines that emphasize guide tones like the third and seventh of each chord. Variants of the ii-V-I expand its expressive potential, including the tritone substitution, where the V7 chord is replaced by another dominant seventh a tritone away, preserving the essential while altering the root for smoother or chromatic color. For instance, , G7 might be substituted with Db7, both sharing the same third and seventh (B and F), which facilitates bop-style lines over rapid changes. Another common variant is the backdoor cadence, structured as bVII7 to I (often approached via iv-bVII7), borrowed from key to provide a plagal-like resolution with a mixolydian flavor, evoking surprise and bluesy tension. These derive briefly from traditional authentic and plagal cadences but are adapted for jazz's harmonic fluidity. Rhythmic flexibility distinguishes jazz cadences from stricter classical forms, with swung rhythms—where eighth notes are performed in a long-short pattern—infusing resolutions with propulsive groove and allowing phrases to breathe or overlap. Elisions, where the end of one phrase coincides with the start of the next, further enhance this, compressing harmonic motion in standards to maintain momentum during solos or heads. In , such as Jerome Kern's "," the tune's chain of ii-V-I progressions (e.g., moving through keys like Ab major to ) exemplifies this, with improvisers like employing swung phrasing and elided turns to heighten intensity. In , exemplified by Miles Davis's "So What" from (1959), cadences shift toward static modal vamps rather than functional progressions, using and mixolydian scales over pedal points for subtle substitutions that imply without traditional dominants, prioritizing atmospheric tension over chordal drive. This approach influenced later improvisers, blending ii-V-I elements with ambiguity for expanded harmonic palettes. In , the I–V–vi– chord progression serves as a ubiquitous that functions as a pseudo-cadence, creating a sense of rather than definitive , often cycling through verses and choruses without strong phrase endings. This incorporates a deceptive motion from V to vi, which delays arrival and contributes to the hypnotic, repetitive quality prevalent in genres like and pop since the mid-20th century. Half cadences, typically ending on V, appear frequently at the close of verses to build tension toward choruses, emphasizing forward drive over closure. The Beatles exemplified these techniques in their hooks, such as the plagal I–IV–I cadence in "Let It Be," which reinforces sectional boundaries while maintaining accessibility for broad audiences. In contemporary electronic dance music (EDM), builds often employ deceptive cadences leading to drops, where rising tension via suspended dominants resolves abruptly into the main groove, heightening emotional impact without traditional harmonic punctuation. Hip-hop production frequently integrates sampled harmonic elements into loops, repurposing fragments from soul or funk sources to create layered, non-linear phrase structures that prioritize rhythmic flow over resolution. Adaptations in modern genres include modal mixtures, borrowing chords like the flat-VI or flat-VII from modes to infuse pop progressions with color and ambiguity, as seen in tracks blending elements for emotional depth. diverges further by eschewing traditional resolutions altogether, favoring sustained drones and that evoke without cadential goal-orientation. Post-2000 trends emphasize loop-based forms, with single-chord repetitions and post-choruses replacing varied cadences to sustain listener engagement in streaming-era pop.
