Short Answer
Overview
A deceptive cadence, also called an interrupted cadence, occurs when a dominant harmony (V or V7) resolves to a chord other than the tonic, most commonly the submediant (vi) in major keys or the subdominant (IV) in minor keys. The effect is a momentary deferral of the expected tonal resolution, creating a sense of surprise while still maintaining forward motion. Although the name suggests deception, the progression follows established rules of functional harmony and is therefore predictable to trained ears.
In tonal music the dominant chord carries a strong pull toward the tonic because of its leading tone and the tritone interval within it. By redirecting that pull to a less stable chord, composers can extend a phrase, prepare a modulation, or add emotional nuance. Deceptive cadences are found in a wide range of repertoire, from Baroque concertos to Romantic symphonies and modern pop songs.
History / Origin
The term “deceptive cadence” entered music theory literature in the early 19th century, alongside other cadence classifications such as perfect, imperfect, and plagal. It derives from the French “cadence trompeuse” and the German “verirrte Kadenz,” both literally meaning “misleading cadence.” The concept was codified in the common‑practice period as theorists like Rameau and later Hugo Riemann described the functional role of the dominant and its alternative resolutions.
How It’s Used
Deceptive cadences appear in any genre that employs functional harmony. In classical and Romantic orchestral works they often conclude a phrase before a new section, while in jazz they may be voiced with extended or altered chords. Pop and rock songs frequently use the V‑vi progression (e.g., G–Em in the key of G major) because it provides a smooth, emotionally resonant shift. The cadence is not limited to a particular instrument; it is realized in piano, guitar, vocal lines, and full orchestration alike, and is notated with ordinary chord symbols or Roman numerals.
Why It Matters
Understanding deceptive cadences helps musicians anticipate and shape phrasing, improvise, and compose more compelling harmonic progressions. For listeners, the unexpected turn creates a moment of tension that can heighten emotional impact. Notable examples include the opening of Beethoven’s Symphony No. 5 (the V–vi move in the development), the aria “Una furtiva lagrima” from Donizetti’s *L’elisir d’amore*, and contemporary songs such as The Beatles’ “Let It Be” where the V–vi cadence adds a bittersweet colour.
Common Misconceptions
A deceptive cadence always resolves to the vi chord.
While V–vi is the most common in major keys, other resolutions such as V–IV in minor keys or V–♭VI in modal contexts also qualify as deceptive.
Deceptive cadences are only used for surprise.
They also serve structural purposes, such as preparing a modulation, extending a phrase, or providing a gentle transition between sections.
FAQ
Can a deceptive cadence occur in minor keys?
Yes. In minor keys the dominant often resolves to the subdominant (iv) or to the major submediant (VI), both of which are considered deceptive resolutions.
Is a deceptive cadence the same as a false cadence?
The terms are synonymous; "false cadence" is an older English translation of the French "cadence trompeuse".
How is a deceptive cadence notated in Roman numeral analysis?
It is written as V–vi (or V–♭VI, V–IV, etc.) with the appropriate key signature and accidentals to show the unexpected chord.
