The Four Main Types of Cadences in Music

Cadences play a crucial role in music, providing points of resolution and closure within a composition. They are chord progressions consisting of at least two chords and are used to mark the end of a musical phrase or section. In this article, we will explore the four main types of cadences: Perfect (or Authentic), Plagal, Imperfect (or Half), and Interrupted (or Deceptive). The information presented here is based on reputable sources such as YouTube, Wikipedia, and Music Theory Academy.

Perfect (Authentic) Cadence

The Perfect Cadence, also known as the Authentic Cadence, is the most definitive and conclusive type of cadence. It typically involves the movement from the dominant chord (V) to the tonic chord (I). This progression creates a sense of resolution and finality, giving the impression of a complete musical phrase or section. In the key of C major, for example, a Perfect Cadence would end on the chord C.

According to the sources, the Perfect Cadence is often described as the cadence that sounds the “most finished.” It provides a strong sense of tonal stability and is frequently used to conclude musical compositions or sections.

Plagal Cadence

The Plagal Cadence, sometimes referred to as the “Amen Cadence,” moves from the subdominant chord (IV) to the tonic chord (I). This cadence is characterized by its softer and more peaceful sound compared to the Perfect Cadence. In traditional hymns, the word “Amen” is often set to a Plagal Cadence at the end.

Just like the Perfect Cadence, the Plagal Cadence also gives a sense of resolution, albeit with a gentler touch. It is considered a more melodic and harmonically stable way to conclude a musical phrase or section.

Imperfect (Half) Cadence

The Imperfect Cadence, also known as the Half Cadence, creates a sense of suspension or incompleteness. It ends on the dominant chord (V) and often leaves listeners with the expectation of further musical development. The Imperfect Cadence can begin on any of the chords I, II, or IV, but it always resolves to the dominant chord (V).

This type of cadence is characterized by its temporary nature, as it doesn’t provide a definitive resolution. Instead, it serves as a pause or a moment of anticipation, signaling that the music is not yet finished and will continue.

Interrupted (Deceptive) Cadence

The Interrupted Cadence, also referred to as the Deceptive Cadence, involves an unexpected resolution. It deviates from the expected progression and surprises the listener by resolving the dominant chord (V) to a chord other than the tonic. This unexpected twist creates a sense of surprise, disruption, or interruption.

The Interrupted Cadence adds variety and interest to a composition by momentarily diverting from the anticipated resolution. It introduces harmonic tension and can be used to create a sense of musical drama or to transition smoothly into a new musical section.

Conclusion

In summary, cadences are essential elements in music that provide points of resolution and closure. The four main types of cadences include the Perfect (Authentic), Plagal, Imperfect (Half), and Interrupted (Deceptive) cadences. Each type carries its distinct characteristics and contributes to the overall musical expression. By understanding and utilizing these cadences, composers and musicians can create a sense of structure, tension, and release within their musical compositions.
