PLAGAL CADENCE

PLAGAL CADENCE: Everything You Need to Know

plagal cadence is a type of musical cadence that has been used for centuries in various forms of music. It is characterized by a final chord that is the tonic of the key, often with a sense of finality and resolution. In this comprehensive guide, we will explore the definition, characteristics, and practical applications of plagal cadence.

Understanding Plagal Cadence

Plagal cadence is a type of cadence that uses the tonic chord as the final chord, often preceded by a dominant chord. This creates a sense of tension and release, as the dominant chord resolves to the tonic chord. The plagal cadence is often used in hymns, chorales, and other types of sacred music.

There are two main types of plagal cadence: the authentic plagal cadence and the plagal cadence. The authentic plagal cadence uses the dominant chord as the second-to-last chord, while the plagal cadence uses the subdominant chord.

Plagal Cadence serves as a crucial element in music theory, particularly in the realm of harmony and counterpoint. It is a fundamental concept that has been studied and applied by musicians, composers, and music theorists across various genres and styles. In this article, we will delve into the intricacies of plagal cadence, analyzing its structure, characteristics, and applications.

Definition and Structure

Plagal cadence, also known as the "Amen cadence," is a type of musical cadence that concludes with a perfect authentic cadence in the plagal key. It consists of a progression that moves from the tonic to the mediant, then to the dominant, and finally to the tonic, often incorporating a perfect fifth or octave in the bass line.

The plagal cadence typically follows a specific pattern, which is as follows:

I - vi - IV - V - I (or I - VI - IV - V)
Where I is the tonic chord, vi is the relative minor chord, IV is the subdominant chord, and V is the dominant chord.

One of the key characteristics of plagal cadence is its use of a subdominant chord, which creates a sense of resolution and finality. This is in contrast to the dominant-based cadence, which often uses a dominant chord to create a sense of tension and release.

Pros and Cons

One of the primary benefits of plagal cadence is its ability to create a sense of resolution and finality. This is particularly useful in hymns, liturgical music, and other forms of sacred music, where the plagal cadence is often used to convey a sense of conclusion and completion.

However, plagal cadence can also be seen as less dramatic or less conclusive than a traditional authentic cadence. This is because the subdominant chord can sometimes create a sense of ambiguity or uncertainty, rather than the clear resolution provided by the dominant chord.

Additionally, plagal cadence can be seen as somewhat formulaic or predictable, particularly when used in repetitive or repetitive musical contexts. This can make it less effective in more complex or nuanced musical settings.

Comparison to Authentic Cadence

Authentic cadence, also known as the "perfect authentic cadence," is a type of cadence that concludes with a perfect authentic cadence in the tonic key. It consists of a progression that moves from the tonic to the dominant, and then back to the tonic, often incorporating a perfect fifth or octave in the bass line.

One of the key differences between plagal and authentic cadence is the use of the subdominant chord in plagal cadence. This creates a sense of resolution and finality, whereas the dominant chord in authentic cadence creates a sense of tension and release.

The following table highlights some of the key similarities and differences between plagal and authentic cadence:

Feature	Plagal Cadence	Authentic Cadence
Final Chord	Perfect authentic	Perfect authentic
Bass Line	Perfect fifth or octave	Perfect fifth or octave
Chord Progression	I - vi - IV - V - I	I - V - I
Character	Resolution and finality	Tension and release

Applications in Music

Plagal cadence is widely used in various musical contexts, including:

Hymns and liturgical music
Classical music, particularly in the Baroque and Classical periods
Choral music, particularly in the Renaissance and Romantic periods
Popular music, particularly in the folk and rock genres

One of the key applications of plagal cadence is in creating a sense of resolution and finality. This is particularly useful in musical contexts where a sense of conclusion and completion is desired, such as in hymns and liturgical music.

Plagal cadence can also be used to create a sense of contrast and surprise. For example, a plagal cadence can be used at the end of a piece, followed by a sudden shift to a new key or musical idea, creating a sense of surprise and tension.

Conclusion

Plagal cadence is a fundamental element of music theory that has been used by musicians and composers across various genres and styles. Its use of a subdominant chord creates a sense of resolution and finality, making it particularly useful in musical contexts where a sense of conclusion and completion is desired.

While plagal cadence has its own set of characteristics and applications, it is often compared to authentic cadence, which creates a sense of tension and release. By understanding the differences and similarities between these two types of cadence, musicians and composers can gain a deeper appreciation for the complexities of music theory and its applications in various musical contexts.
