What Does Sequitur Mean? Unlocking the Secrets of Musical Harmony

In the world of music, there exists a fundamental concept that has been guiding composers and musicians for centuries. This concept is known as "sequitur." In Latin, "sequitur" translates to "it follows," but in musical terminology, it holds much more significance. In this article, we will delve into the meaning of sequitur and explore its importance in music theory.

What is Sequitur?

Sequitur refers to the process of connecting two or more melodic phrases, harmonies, or sections of a piece of music seamlessly. It involves creating a sense of continuity by linking distinct musical ideas together, often using various techniques such as repetition, contrast, and resolution. Sequitur is essential in creating cohesive and engaging musical structures.

Types of Sequiturs

There are several types of sequiturs, each serving a unique purpose:

Harmonic Sequitur: This type of sequitur focuses on the harmonies used to connect two or more sections. Harmonic sequences can be based on common chord progressions, modulation, or even surprise changes.
Melodic Sequitur: In this type of sequitur, the melody is the primary focus. Melodic connections can be achieved through repetition, fragmentation, or reharmonization.
Structural Sequitur: This type of sequitur involves connecting different sections or movements within a larger work. Structural sequences can create a sense of unity and coherence.

Why is Sequitur Important?

Sequitur plays a vital role in music composition for several reasons:

Creates Cohesion: By linking distinct musical ideas, sequitur helps to create a sense of unity and cohesion throughout a piece.
Guides the Listener: Effective sequencing guides the listener's ear through the musical narrative, enhancing their emotional connection to the music.
Adds Depth: Sequitur allows composers to explore different themes, motifs, and harmonies, adding depth and complexity to their work.

Examples of Sequitur in Music

Many famous composers have employed sequitur in their works:

Beethoven's Symphony No. 5: The iconic opening four-note motif is repeated and varied throughout the symphony, creating a sense of unity and drama.
Mozart's Requiem Mass in D minor: The reprise of the Introit theme in the Lacrimosa movement exemplifies harmonic sequitur, linking distinct sections together.
The Beatles' "Hey Jude": The iconic "na-na-na" refrain is repeated and varied throughout the song, creating a sense of unity and familiarity.

Conclusion

Sequitur is a fundamental concept in music theory that helps composers create cohesive, engaging, and meaningful musical structures. By understanding sequitur, musicians can develop their skills in connecting distinct musical ideas and crafting compelling compositions. Whether you're a seasoned composer or an aspiring musician, grasping the meaning of sequitur will enhance your appreciation and creation of music.

In the words of renowned composer Arnold Schoenberg, "Sequitur is not just a matter of linking things together; it's a matter of creating a musical narrative that tells a story." By embracing the power of sequitur, musicians can craft stories that captivate audiences for generations to come.
