Cadence

For other uses, see Cadence (disambiguation).

In Western musical theory, a cadence (from Latin cadentia 'a falling') is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards.^[2] A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music.^[3] A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase.^[4] A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives. While cadences are usually classified by specific chord or melodic progressions, the use of such progressions does not necessarily constitute a cadence—there must be a sense of closure, as at the end of a phrase. Harmonic rhythm plays an important part in determining where a cadence occurs. The word "cadence" sometimes slightly shifts its meaning depending on the context; for example, it can be used to refer to the last few notes of a particular phrase, or to just the final chord of that phrase, or to types of chord progressions that are suitable for phrase endings in general.

The final two chords present an authentic (or perfect) cadence with roots in the bass lines and the tonic note in the highest voice of the final chord): the three chords are a ii–V–I progression in C major, in four-part harmony^[1]

Cadences are strong indicators of the tonic or central pitch of a passage or piece.^[2] The musicologist Edward Lowinsky proposed that the cadence was the "cradle of tonality".^[5]

Common classifications

Cadences are divided into four main types, according to their harmonic progression: authentic (typically perfect authentic or imperfect authentic), half, plagal, and deceptive. Typically, phrases end on authentic or half cadences, and the terms plagal and deceptive refer to motion that avoids or follows a phrase-ending cadence. Each cadence can be described using the Roman numeral system of naming chords.

Authentic cadence

 

The final two chords represent a perfect authentic cadence; from Beethoven's Piano Sonata No. 8, mvmt. III, mm. 16–17.^[7]

An authentic cadence is a cadence from the dominant chord (V) to the root chord (I). During the dominant chord, a seventh above the dominant may be added to create a dominant seventh chord (V⁷); the dominant chord may also be preceded by a cadential ⁶
₄ chord. The Harvard Concise Dictionary of Music and Musicians says, "This cadence is a microcosm of the tonal system, and is the most direct means of establishing a pitch as tonic. It is virtually obligatory as the final structural cadence of a tonal work."^[2] Authentic cadences are generally classified as either perfect or imperfect. The phrase perfect cadence is sometimes used as a synonym for authentic cadence but can also have a more precise meaning depending on the chord voicing.

Perfect authentic cadence

In a perfect authentic cadence (PAC), the chords are in root position – that is, the roots of both chords are in the bass – and the tonic is in the highest voice of the final chord. This is generally considered the strongest type of cadence and often found at structurally defining moments.^[8] Music theorist William Caplin writes that the perfect authentic cadence "achieves complete harmonic and melodic closure."^[9]

 

Imperfect authentic cadence

There are three types of imperfect authentic cadences (IAC):^[10]

• Root position IAC (shown below): Similar to a perfect authentic cadence, but the highest voice is not the tonic.

 

• Inverted IAC: Similar to a perfect authentic cadence, but one or both chords are inverted.
• Leading-tone IAC: The penultimate (V) chord is replaced with a chord based on the leading-tone (vii^o chord).

Evaded cadence

An evaded cadence moves from a dominant seventh third inversion chord (V⁴
₂) to a first inversion tonic chord (I⁶
).^[11] Because the seventh of the dominant chord must fall stepwise to the third of the tonic chord, it forces the cadence to resolve to the less stable first inversion chord. To achieve this, a root position V usually changes to a V⁴
₂ right before resolution, thereby "evading" the root-position I chord that would usually follow a root-position V. (See also inverted cadence below.)

 

Half cadence

A half cadence (also called an imperfect cadence or semicadence) is any cadence ending on V, whether preceded by II (V of V), ii, vi, IV, or I—or any other chord. Because it sounds incomplete or suspended, the half cadence is considered a weak cadence that calls for continuation.^[12]

 

Several types of half cadences are described below.

Phrygian half cadence

 

The last two chords represent a Phrygian half cadence in Bach's four-part chorale, Schau, lieber Gott, wie meine Feind^[13]

A Phrygian half cadence is a half cadence iv⁶–V in minor, so named because the semitonal motion in the bass (sixth degree to fifth degree) resembles the half-step heard in the ii–I of the 15th-century cadence in the Phrygian mode. Due to its being a survival from modal Renaissance harmony this cadence gives an archaic sound, especially when preceded by v (v–iv⁶–V).^[14] A characteristic gesture in Baroque music, the Phrygian cadence often concluded a slow movement immediately followed by a faster one.^[15] With the addition of motion in the upper part down to the sixth degree before rising to the tonic, it becomes the Landini cadence.^[2]

 

Lydian cadence

A Lydian cadence is similar to the Phrygian half cadence, involving iv⁶–V in the minor. The difference is that in the Lydian cadence, the whole iv⁶ is raised by a half step. In other words, the Phrygian half cadence begins with the first chord built on scale degree  , while the Lydian half cadence is built on the scale degree ♯ .^{[citation needed]}

 

Burgundian cadences

Burgundian cadences became popular in Burgundian music. Note the parallel fourths between the upper voices.^[16]

 

Plagal half cadence

The rare plagal half cadence involves a I–IV progression. Like an authentic cadence (V–I), the plagal half cadence involves an ascending fourth (or, by inversion, a descending fifth).^[17] The plagal half cadence is a weak cadence, ordinarily at the ending of an antecedent phrase, after which a consequent phrase commences. One example of this use is in "Auld Lang Syne". But in one very unusual occurrence – the end of the exposition of the first movement of Brahms' Clarinet Trio, Op. 114—it is used to complete not just a musical phrase but an entire section of a movement.^[18]

Plagal cadence

A plagal cadence is a cadence from IV to I. It is also known as the Amen cadence because of its frequent setting to the text "Amen" in hymns.

 

Minor plagal cadence

A minor plagal cadence, also known as a perfect plagal cadence, uses the minor iv instead of a major IV. With a very similar voice leading to a perfect cadence, the minor plagal cadence is a strong resolution to the tonic.

 

Moravian cadence

The Moravian cadence, which can be found in the works of Leoš Janáček and Bohuslav Martinů amongst others, is a form of plagal cadence in which the outer notes of the first chord each move inwards by a tone to the second. (IV^add6 → I⁶).^[19] An early suggestion of the Moravian cadence in classical music occurs in Antonín Dvořák’s New World Symphony.^[20]

Deceptive cadence

 

A deceptive cadence in the second movement of Mozart's Piano Sonata No. 10^[12]

"A cadence is called 'interrupted', 'deceptive' or 'false' where the penultimate, dominant chord is not followed by the expected tonic, but by another one, often the submediant."^[21] This is the most important irregular resolution,^[22] most commonly V⁷–vi (or V⁷–♭VI) in major or V⁷–VI in minor.^[22][23] This is considered a weak cadence because of the "hanging" (suspended) feeling it invokes.

 

At the beginning of the final movement of Gustav Mahler's 9th Symphony, the listener hears a string of many deceptive cadences progressing from V to IV⁶.^{[citation needed]}

One of the most striking uses of this cadence is in the A-minor section at the end of the exposition in the first movement of Brahms' Third Symphony. The music progresses to an implied E minor dominant (B⁷) with a rapid chromatic scale upwards but suddenly sidesteps to C major. The same device is used again in the recapitulation; this time the sidestep is—as one would expect—to F major, the tonic key of the whole Symphony.^{[citation needed]}

The interrupted cadence is also frequently used in popular music. For example, the Pink Floyd song "Bring the Boys Back Home" ends with such a cadence (at approximately 0:45–50).^{[citation needed]}

Other classifications

Inverted cadence

An inverted cadence (also called a medial cadence) inverts the last chord. It may be restricted only to the perfect and imperfect cadence, or only to the perfect cadence, or it may apply to cadences of all types.^[24] To distinguish them from this form, the other, more common forms of cadences listed above are known as radical cadences.^[25]

Rhythmic classifications

Cadences can also be classified by their rhythmic position:

• A metrically accented cadence has its final note in a metrically strong position, typically the downbeat of a measure.
• A metrically unaccented cadence has its final note in a metrically weak position, for instance, after a long appoggiatura.

Metrically accented cadences are considered stronger and are generally of greater structural significance. In the past, the terms masculine and feminine were sometimes used to describe rhythmically "strong" or "weak" cadences, but this terminology is no longer acceptable to some.^[26] Susan McClary has written extensively on the gendered terminology of music and music theory in her book Feminine Endings.^[27]

The example below shows a metrically unaccented cadence (IV–V–I). The final chord is postponed to fall on a weak beat.^[28]

 

Picardy third

A Picardy third (or Picardy cadence) is a harmonic device that originated in Western music in the Renaissance era. It refers to the use of a major chord of the tonic at the end of a musical section that is either modal or in a minor key. The example below shows a picardy third in the final chord, from J.S. Bach's Jesu, meine Freude (Jesus, My Joy), mm. 12–13.^[29]

 

Upper leading-tone cadence

This example from a well-known 16th-century lamentation shows a cadence that appears to imply the use of an upper leading-tone, a debate over which was documented in Rome c. 1540.^[30] The final three written notes in the upper voice are printed B–C–D, in which case the customary trill on the second to last note should be played using D and C. However, convention implied that the written C should be played as a C♯ in this context, and a cadential trill of a whole tone on the second to last note would then require a D♯/E♭, the upper leading-tone of D♮. Presumably, the debate was over whether to use D♯–C♯ or D–C♯ for the trill.

 

In medieval and Renaissance polyphony

Medieval and Renaissance cadences are based upon dyads rather than chords. The first theoretical mention of cadences comes from Guido of Arezzo's description of the occursus in his Micrologus, where he uses the term to mean where the two lines of a two-part polyphonic phrase end in a unison.

Clausula vera

 

A clausula vera cadence from Lassus's Beatus homo, mm. 34–35.^[31]

A clausula or clausula vera ("true close") is a dyadic or intervallic, rather than chordal or harmonic, cadence. In a clausula vera, two voices approach an octave or unison through stepwise motion^[31] in contrary motion.

 

 

A three-voice clausula vera from Palestrina's Magnificat Secundi Toni: Deposuit potentes, mm. 27–28.^[31]

In three voices, the third voice often adds a falling fifth creating a cadence similar to the authentic cadence in tonal music.^[31]

 

According to Carl Dahlhaus, "as late as the 13th century the half step was experienced as a problematic interval not easily understood, as the remainder between the perfect fourth and the ditone:^[32]

${\displaystyle {\frac {\frac {4}{3}}{\left({\frac {9}{8}}\right)^{2}}}={\frac {256}{243}}}$ 

In a melodic half step, listeners of the time perceived no tendency of the lower tone toward the upper, or the upper toward the lower. The second tone was not the 'goal' of the first. Instead, musicians avoided the half step in clausulas because, to their ears, it lacked clarity as an interval. Beginning in the 13th century, cadences begin to require motion in one voice by half step and the other a whole step in contrary motion.

Plagal cadence

A plagal cadence was found occasionally as an interior cadence, with the lower voice in two-part writing moving up a perfect fifth or down a perfect fourth.^[33]

 

Rest

A rest in one voice may also be used as a weak interior cadence.^[33] The example below, Lassus's Qui vult venire post me, mm. 3–5, shows a rest in the third measure.

 

Evaded cadence

In counterpoint, an evaded cadence is one where one of the voices in a suspension does not resolve as expected, and the voices together resolve to a consonance other than an octave or unison^[34] (a perfect fifth, a sixth, or a third).

Corelli cadence

The Corelli cadence, or Corelli clash, named for its association with the violin music of the Corelli school, is a cadence characterized by a major and/or minor second clash between the tonic and the leading-tone or the tonic and supertonic. An example is shown below.^[35]

 

English cadence

Another "clash cadence", the English cadence, is a contrapuntal pattern particular to the authentic or perfect cadence. It features the blue seventh against the dominant chord,^[36] which in the key of C would be B♭ and G–B♮–D. Popular with English composers of the High Renaissance and Restoration periods in the 16th and 17th centuries, the English cadence is described as sounding archaic^[37] or old-fashioned.^[38] It was first given its name in the 20th century.

The hallmark of this device is the dissonant augmented octave (compound augmented unison) produced by a false relation between the split seventh scale degree, as shown below in an excerpt from O sacrum convivium by Thomas Tallis. The courtesy accidental on the tenor's G♮ is editorial.

 

Landini cadence

A Landini cadence (also known as a Landini sixth, Landini sixth cadence, or under-third cadence^[39]) is a cadence that was used extensively in the 14th and early 15th century. It is named after Francesco Landini, a composer who used them profusely. Similar to a clausula vera, it includes an escape tone in the upper voice, which briefly narrows the interval to a perfect fifth before the octave.

 

Common practice period

The classical and romantic periods of musical history provide many examples of the way the different cadences are used in context.

Authentic cadences and half cadences

Mozart’s Romanze from his Piano Concerto No. 20 follows a familiar pattern of a pair of phrases, one ending with a half (imperfect) cadence and the other with an authentic cadence:

Mozart Romanze from Piano Concerto 20

 

Mozart Romanze from Piano Concerto 20

The presto movement from Beethoven’s String Quartet Op 130 follows the same pattern, but in a minor key:

Beethoven Presto from Quartet Op. 130

 

Beethoven Presto from Quartet Op. 130

Plagal cadences

The Hallelujah Chorus from Handel’s Messiah culminates powerfully with an iterated plagal cadence:

Handel, Messiah, Hallelujah Chorus closing bars

 

Handel, Messiah, Hallelujah Chorus closing bars

Debussy’s prelude ‘La Fille aux Cheveux de Lin’ contains a plagal cadence in its 2nd and 3rd bars :

Debussy la Fille aux cheveux de lin, bars 1-4

 

Debussy La Fille aux Cheveux de Lin, bars 1-4

One of the most famous endings in all music is found in the concluding bars of Wagner’s opera Tristan und Isolde, where the dissonant chord in the opening phrase of the opera is finally resolved "three enormous acts and five hours later"^[40] in the form of a minor plagal cadence:

Wagner, Tristan, Liebestod closing bars

 

Wagner, Tristan, Liebestod closing bars

Deceptive cadences

In Bach's harmonization of the chorale ‘Wachet auf’, a phrase ending in a deceptive cadence repeats with the cadence changed to an authentic one:

From Bach chorale, Wachet auf

 

From Bach chorale, Wachet auf

The exposition of the first movement of Beethoven’s Piano Sonata No. 21 (The Waldstein Sonata), Op. 53 features a minor key passage where an authentic (perfect) cadence precedes a deceptive (interrupted) one:

Beethoven Piano Sonata 21, 1st movement, bars 78-84

 

Beethoven Piano Sonata 21, 1st movement, bars 78–84

Dvořák’s Slavonic Dance, Op. 72, No. 2 features deceptive (interrupted), half (imperfect) and authentic (perfect) cadences within its first sixteen bars:

Dvořák Slavonic Dance Op 72, No. 2

 

Dvořák Slavonic Dance Op 72, No. 2

Debussy's Prelude “La fille aux cheveux de lin” (see also above) concludes with a passage featuring a deceptive (interrupted) cadence that progresses, not from V–VI, but from V–IV:

Debussy, La Fille aux cheveux de lin, bars 26–29

 

Debussy, La Fille aux cheveux de lin, bars 26–29

Some varieties of deceptive cadence that go beyond the usual V–VI pattern lead to some startling effects. For example, a particularly dramatic and abrupt deceptive cadence occurs in the second Presto movement of Beethoven’s Piano Sonata No. 30, Op. 109, bars 97–112, "a striking passage that used to pre-occupy theorists".^[41] The music at this point is in B minor, and carries the expectation is that the chord of F sharp (Chord V) will be followed by the tonic chord of B. However, "Dynamics become softer and softer; dominant and tonic chords of B minor appear isolated on the first beat of a bar, separated by silences: until in sudden fortissimo ... the recapitulation bursts on us in the tonic E minor, the B minor dominants left unresolved."^[42]

Beethoven Piano Sonata Op 109, 2nd movement, bars 97–112

 

Beethoven Piano Sonata Op 109, 2nd movement, bars 97–112

An equally startling example occurs in J.S. Bach's Toccata and Fugue in F major, BWV 540:

Bach Toccata in F, BWV 540 bars 197–207

 

Bach Toccata in F, BWV 540 bars 197–207

According to Richard Taruskin, in this Toccata, "the already much-delayed resolution is thwarted (m204) by what was the most spectacular 'deceptive cadence' anyone had composed as of the second decade of the eighteenth century ... producing an especially pungent effect."^[43] Hermann Keller describes the effect of this cadence as follows: "the splendour of the end with the famous third inversion of the seventh chord, who would not be enthralled by that?"^[44]

Chopin's Fantaisie, Op. 49, composed over a century later in 1841, features a similar harmonic jolt:

Chopin Fantaisie in F minor, Op. 49

 

Chopin Fantaisie in F minor, Op. 49

A deceptive cadence is a useful means for extending a musical narrative. In the closing passage of Bach’s Prelude in F minor from Book II of the Well-Tempered Clavier, the opening theme returns and seems headed towards a possible final resolution on an authentic (perfect) cadence. What the listener may expect is:

Bach, Prelude in F minor, bars 57–60 with expected conclusion

 

Bach, Prelude in F minor, bars 57–60 with expected conclusion

Instead, at bar 60, Bach inserts a deceptive cadence (V–VI in F minor), leading to a lengthy digression of some dozen bars before reaching resolution on the final (V–I) cadence.

Bach, Prelude in F minor bars 57–70

 

Bach, Prelude in F minor bars 57–70

A similar passage occurs at the conclusion of Mozart's Fantasia in D minor, K397:

Mozart Fantasia on D minor K397 closing bars

 

Mozart Fantasia on D minor K397 closing bars

Jazz

Cadences in jazz are usually simply called cadences, as in common practice harmony. However, a certain category of cadence is referred to as a turnaround (originally called a "turnback" which is more accurate); this is when a cadence functions as a return to an already existing part of a song form such as AABA. In an AABA form, there are two turnbacks: at the end of the first A (A1) in order to repeat it (A2), and at the end of the B section in order to play the A a third time (A3). (The transition from the second A to the B is not a turnback, because the B section is being heard for the first time.)

Half-step cadences are common in jazz if not cliché.^{[clarification needed][45]} For example, the ascending diminished seventh chord half-step cadence, which—using a secondary diminished seventh chord—creates momentum between two chords a major second apart (with the diminished seventh in between).^[46]

 

The descending diminished seventh chord half-step cadence is assisted by two common tones.^[46]

 

Rhythmic cadence

Cadences often include (and may be emphasized or signalled by) a change in the prevailing rhythmic pattern; in such cases the final note of the cadence usually takes more time (a longer note value, or followed by a rest, or both), and within a piece of music the cadences may also share a rhythmic pattern that is characteristic of the cadences in that piece. This method of ending a phrase with some distinctive rhythmic pattern has been called a "rhythmic cadence"; rhythmic cadences continue to function without harmony or melody, for example at the ends of phrases in music for drums. Some styles of music rely on frequent regular rhythmic cadences as a unifying feature of that style.^[4] The example below shows a characteristic rhythmic cadence (i.e. many of the cadences in this piece share this rhythmic pattern) at the end of the first phrase (in particular the last two notes and the following rest, contrasted with the regular pattern set up by all the notes before them) of J.S. Bach's Brandenburg Concerto No. 3 in G major, BMV 1048, mvmt. I, mm. 1–2:
