Definition
In the deceptive cadence (or interrupted cadence), the dominant does not go to the expected tonic but to another chord, almost always one that shares at least one note with the tonic. The ear expects closure; the music instead continues. It is one of the most powerful tools for extending a phrase and creating surprise.
The classic form: V → vi
In C: G7 → Am.
- B (leading tone) rises to C, as in the perfect cadence
- F (seventh) falls to E
- D falls to C: in Am the third is doubled (C), a textbook rule that avoids parallel fifths and octaves with the bass
- G → A in the bass (the bass rises by step instead of leaping to C)
Am shares C and E with C major: it is the representative of the tonic (Tp in Riemann).
In minor: V → VI
In A minor: E7 → F. The leading tone G# rises to A, the bass E rises to F. It is more dramatic: the major VI "lights up" the minor for an instant.
Variants
| Variant | C major | Effect |
|---|---|---|
| V – vi | G – Am | standard, melancholic |
| V – bVI | G – Ab | chromatic, surprising, "epic" (borrowed from the minor) |
| V – IV6 | G – F/A | bass G → A as in V – vi, but subdominant harmony; widely used in pop |
| V – iii | G – Em | weak, "suspended"; typical of the royal road (IVmaj7 – V7 – iii7 – vi) |
| V – I6 | G – C/E | almost authentic, but not conclusive |
| V – V/V or V – vii°7/V | G – D7 or G – F#°7 | "relaunches" toward a new cadence |
| V – bII | G – Db | Neapolitan, very rare and theatrical |
| V7 – IV (rock) | G – F | "backward deception," typical of blues-rock |
Real examples
- Leonard Cohen, Hallelujah (1984, C): the text of the first verse describes exactly the harmonic succession you hear: the fourth, the fifth, and then a "fall" to the minor, that is, G → Am, a deceptive cadence, followed by F.
- In Bach chorales the deceptive cadence often appears in the penultimate phrase, to postpone the closure until the last.
- Royal road J-pop (IVmaj7 – V7 – iii7 – vi): V7 → iii7 is a "weak" deception repeated endlessly: the tonic never arrives.
- In many pop ballads the final chorus is extended with V – vi – IV – V – I: the deception buys two bars of climax before the close.
Compositional use
- Phrase extension: an 8-bar phrase → 10 or 12 bars thanks to a deception on the cadence.
- Emotional contrast: on the key word of the lyrics (deception = "but...").
- Climax: V – bVI – bVII – I is a "stadium" ending that starts from a chromatic deception.
Exercise for the producer
- Write a 4-bar phrase that ends on G7 → C.
- Repeat it: the second time replace the C with Am, then add F – G – C (6-bar phrase).
- Try the other variants in the table (Ab, F/A, Em) and listen to the different kind of "disappointment."
- In the mix, on the deceptive chord you can open a filter or add a crash: the listener feels that "something has changed."
