A cadence is a short chord sequence that ends a musical phrase, giving it a sense of pause, breath, or full-stop. If you have ever wondered what is a cadence, think of it as musical punctuation: some cadences act like a firm period at the end of a sentence, while others feel like a comma that leaves you hanging. Understanding cadences is one of the fastest ways to make your chord progressions feel intentional instead of random.
Almost every song you know leans on cadences to shape its verses, choruses, and endings. Once you can hear them, you will start noticing exactly where a melody “lands” and why certain progressions feel finished while others beg to keep going. Below, we walk through the four main cadence types, spell out the actual chords in the key of C major, and show you how to put them to work in your own tracks.
What is a cadence, and why does it matter?
In music theory, a cadence is the final two chords (sometimes more) of a phrase, chosen for the specific feeling of resolution — or lack of it — that they create. The word comes from the Latin cadere, “to fall,” and originally described the way a melody line settles at the end of a phrase.
Cadences matter because they organise time. A four-bar phrase that ends on a strong cadence feels complete, so the listener relaxes. A phrase that ends on an unstable cadence pulls the ear forward into the next section. Songwriters use this tension and release to keep verses moving and to make choruses feel like an arrival. Get your cadences right and even a simple loop starts to breathe.
We will use C major for every example because it has no sharps or flats, which keeps the chords easy to read. Here is the full set of triads in C major so you can follow along:
- I = C (C–E–G)
- ii = Dm (D–F–A)
- iii = Em (E–G–B)
- IV = F (F–A–C)
- V = G (G–B–D)
- vi = Am (A–C–E)
- vii° = Bdim (B–D–F)
The authentic cadence: V–I, the strongest ending
The authentic cadence moves from the dominant chord (V) to the tonic (I). In C major that is G to C. This is the most conclusive cadence in Western music because the V chord contains the leading tone (B), which pulls hard upward into the tonic note C. When you hear a song end with a satisfying, “we’re home” thud, you are almost always hearing a V–I.
Theorists split it into two grades of strength. A perfect authentic cadence (PAC) has both chords in root position and the melody landing on the tonic note — the fully closed, definitive version you hear at the end of a hymn or a classical piece. An imperfect authentic cadence (IAC) is a softer variant: one of the chords is inverted, or the melody ends on the third or fifth instead of the tonic, so it still resolves but with less finality.
Try playing G then C on a keyboard, ending with C in the top voice. That decisive landing is the sound of resolution itself. If you want to experiment with voicings, the free Violet Recording virtual piano lets you sound out each chord before you commit.
The plagal cadence: IV–I, the “Amen” sound
The plagal cadence goes from the subdominant (IV) to the tonic (I) — F to C in C major. It is nicknamed the “Amen cadence” because it is the exact progression sung on the word “Amen” at the end of countless hymns.
The plagal cadence still resolves to the tonic, so it feels finished, but it is gentler and warmer than the authentic cadence. Because IV does not contain the leading tone, there is no sharp upward pull — instead the resolution feels like settling down rather than clicking shut. Gospel, soul, and rock ballads lean on the plagal sound for its rounded, reassuring quality. You will often hear it tacked on after a V–I as a final “amen” flourish, which is why so many big ballad endings feel doubly resolved.
The half cadence: ending on V, the musical comma
A half cadence is any phrase that ends on the dominant chord (V) rather than resolving to it. Common approaches include I–V (C to G), ii–V (Dm to G), or IV–V (F to G). Because the phrase stops on the unstable V chord, it sounds unfinished — like a question waiting for an answer.
This is the “comma” of cadences. Songwriters use half cadences at the end of a first phrase so the second phrase feels like a reply. A classic pop structure pairs a first line that ends on a half cadence (ending on G) with a second line that closes on an authentic cadence (ending on C), creating a satisfying call-and-response over eight bars. If you have a verse melody that feels too self-contained, ending the first half on V is an easy way to pull the listener onward.
The deceptive cadence: V–vi, the plot twist
The deceptive cadence (also called an interrupted cadence) sets up a V chord as if it is about to resolve to the tonic — then swerves to vi instead. In C major that is G to Am rather than the expected G to C.
The trick works because vi (Am) shares two notes with the tonic C chord — both contain C and E — so the ear is partly satisfied but denied the true “home” note. The result is a gentle surprise, a bittersweet turn that often reads as wistful or unresolved. Composers use it to extend a phrase and delay the real ending, and pop writers use it to keep a chorus from resolving too soon. Play G–C and then play G–Am back to back and you will feel the difference instantly: one closes the door, the other leaves it ajar.
How the four cadences compare
Here is the quick reference for every cadence in C major:
- Authentic (V–I): G → C — strongest resolution, a full stop.
- Plagal (IV–I): F → C — warm, gentle resolution, the “Amen” sound.
- Half (ends on V): e.g. C → G — unresolved, a comma or question.
- Deceptive (V–vi): G → Am — a surprise turn that avoids home.
To hear how these chords relate within a key, it helps to see them mapped out. The circle of fifths tool shows why V sits a fifth above the tonic and pulls so strongly toward it, and the scale and chord finder gives you the diatonic chords for any key so you can transpose these cadences out of C major.
Using cadences in your own songwriting
Start by placing an authentic cadence at the end of your chorus so it lands with authority. Then experiment with a half cadence at the end of your verse’s first phrase to keep momentum building toward the second phrase. When you want an emotional lift near the end of a bridge, try a deceptive cadence to delay resolution before finally paying it off with a strong V–I.
A practical exercise: take a four-chord loop such as I–V–vi–IV (C–G–Am–F) and notice that the G–Am move inside it is itself a deceptive cadence, which is part of why that progression feels endlessly loopable — it never fully resolves. Swap the last chord for C and suddenly the loop wants to stop. Small changes at the cadence point completely change how a section feels.
Once you have a progression you like, you can sketch a full arrangement around it fast. If you want to hear an idea as a finished track before you produce it properly, tools like Solmi can turn a chord idea into a rough demo so you can test whether your cadences land the way you hoped.
Cadences are a small piece of theory with an outsized payoff. Learn to hear the four types, practise spotting them in songs you love, and your own writing will gain a sense of shape and direction almost immediately. For more foundational lessons, browse the Theory & Songwriting hub.
Frequently asked questions
What is the difference between a perfect and an imperfect cadence?
A perfect authentic cadence is a V–I where both chords are in root position and the melody ends on the tonic note, giving the most complete resolution. An imperfect cadence is weaker — either a chord is inverted or the melody ends on a note other than the tonic. Note that in British theory teaching, “imperfect cadence” often refers to what Americans call a half cadence (ending on V), so always check which system a source is using.
What is the most common cadence in pop music?
The authentic cadence, V–I, is the most common because it delivers the clearest sense of resolution. In C major that is G to C. Pop songs frequently combine it with a plagal (IV–I) or deceptive (V–vi) cadence to add colour, but the V–I remains the backbone of choruses and song endings across nearly every genre.
Can a cadence use seventh chords instead of triads?
Yes. Adding a seventh to the dominant — turning G into G7 (G–B–D–F) — actually strengthens an authentic cadence, because the extra note (F) creates a tritone with the leading tone that pulls even harder toward the tonic. Jazz and R&B lean heavily on seventh and extended chords at cadence points to add richness while keeping the underlying V–I motion intact.
