Sequence: A musical technique involving the repetition of a melodic motif or harmonic progression at different pitch levels within the same composition.

Context and Significance

Sequences are integral in creating a sense of movement and development in music. They are frequently employed in classical compositions, where they add dynamic tension and drive. In baroque music, sequences are often used to modulate between keys, providing a bridge in musical storytelling. They are also prominent in contemporary genres, including pop and jazz, where they enhance the harmonic texture and emotional impact of a piece.

Historical Background

The concept of the sequence can be traced back to the Baroque period, where it became a defining feature in the works of composers like J.S. Bach and Handel. Sequences allowed composers to explore new harmonic landscapes and were often used to elaborate on a theme. Over time, the use of sequences has evolved, becoming a staple in the musical vocabulary of many genres, shaping the development of Western music theory.

Examples

In Bach’s “Prelude in C Major” from The Well-Tempered Clavier, sequences are employed to create a cascading effect that carries the listener through a series of modulations. Similarly, the use of sequences in Vivaldi’s “The Four Seasons” adds drama and excitement, guiding the listener through the changing scenes depicted in the concertos. In modern music, sequences can be found in jazz improvisations, where they serve as a tool for exploring new melodic ideas.
