An authentic cadence, often referred to as a perfect cadence, is a musical term that describes the strong resolution of chords, typically moving from the V (dominant) chord to the I (tonic) chord, creating a sense of finality in a piece of music. This harmonic progression is fundamental in Western music, often used at the end of phrases or sections to convey closure or completeness. Recognizing and understanding authentic cadences is essential for aspiring musicians, as it enhances their composition and performance skills, ensuring they can effectively convey emotions in their music.

Send FeedbackIn music theory, the term authentic cadence refers to a specific type of chord progression that resolves tension and creates a sense of closure. This cadence is known for providing a strong and definitive ending to a musical phrase, often highlighting the key of the piece. The most common authentic cadence is a progression from the dominant chord (V) to the tonic chord (I). In classical music, the authentic cadence serves as a crucial element in establishing tonal resolution, making it one of the foundational ideas in harmonic progression.
Authentic Cadence: A harmonic progression that typically moves from a dominant chord (V) to the tonic chord (I), creating a sense of resolution and closure within a musical piece.
A simple example of an authentic cadence can be seen in the key of C major. In this case, the dominant chord G major (G-B-D) resolves to the tonic chord C major (C-E-G). This transition can be expressed musically as:
| G Major (V) | → | C Major (I) |
Try identifying authentic cadences in your favorite songs; they often occur at the end of phrases or sections to signal closure.
Exploring even deeper, authentic cadences can be classified into two types: perfect authentic cadence (PAC) and imperfect authentic cadence (IAC).
A perfect authentic cadence (PAC) is a specific type of harmonic progression widely recognized in music theory for its strong sense of resolution. It typically consists of a movement from the dominant chord (V) to the tonic chord (I), both in root position, and the tonic note must be the highest pitch in the final chord. This specific arrangement creates a very satisfying and conclusive sound at the end of a musical phrase or section. For example, in the key of C major, a PAC would move from the G major chord (G-B-D) to the C major chord (C-E-G). The clarity and strength of this progression make it a favorite among composers to denote the end of a musical idea.
Perfect Authentic Cadence (PAC): A harmonic progression where the dominant chord (V) moves to the tonic chord (I), both in root position, and the tonic is the highest tone in the final chord, conveying a strong sense of resolution.
An example of a perfect authentic cadence in music can be outlined as follows:
| G Major (V) | → | C Major (I) |
When composing, always prioritize using a perfect authentic cadence at the end of phrases for a strong closure effect.
A perfect authentic cadence holds significant importance in various musical contexts. This progression not only brings about a sense of completion but also reinforces the key of the piece, establishing what is known as tonic stability.Here are some key points about perfect authentic cadences:
An imperfect authentic cadence (IAC) is a type of harmonic progression that provides a sense of resolution but is less definitive than a perfect authentic cadence (PAC). This cadence typically involves a movement from the dominant chord (V) to the tonic chord (I), but differs in that either the chords are not in root position, or the highest note in the tonic chord does not include the tonic pitch. An IAC often creates a feeling of continuation rather than closure, making it useful for bridging sections or phrases within a piece.
Imperfect Authentic Cadence (IAC): A harmonic progression from the dominant chord (V) to the tonic chord (I) that lacks the characteristics of a perfect authentic cadence, either by being in an inverted position or missing the tonic note in the highest voice.
One common example of an imperfect authentic cadence is found in the key of C major:
| G Major (V) | → | C Major (I) |
To enhance musical phrases, try incorporating imperfect authentic cadences to create anticipation, keeping listeners engaged instead of providing immediate closure.
Understanding imperfect authentic cadences can greatly enrich listening and compositional skills. These cadences serve various stylistic purposes in music:
The distinction between perfect authentic cadence (PAC) and imperfect authentic cadence (IAC) plays a crucial role in understanding harmonic progressions in music. Both cadences move from the dominant chord (V) to the tonic chord (I), but they achieve different emotional effects and levels of resolution. By recognizing the characteristics of each, musicians and composers can better utilize them to create desired outcomes in their music.
Perfect Authentic Cadence (PAC): A progression where the dominant chord (V) resolves to the tonic chord (I), both in root position, with the tonic note as the highest tone, providing a strong sense of resolution.
Imperfect Authentic Cadence (IAC): A progression from the dominant chord (V) to the tonic chord (I) that lacks the characteristics of a perfect authentic cadence, either through inversion of the chords or by not having the tonic in the highest voice.
In the key of C major, a PAC can be illustrated with the following progression:
| G Major (V) | → | C Major (I) |
| G Major (V) | → | C/E (I) |
Experiment with using imperfect authentic cadences at the end of sections to maintain listener interest by avoiding formulas of complete closure.
Delving deeper into the applications of both cadences reveals their distinct roles in musical storytelling.
