What is a sequence in music?

A sequence in music is a melodic or harmonic pattern that is repeated at a higher or lower pitch level. Sequences can vary in length and complexity, and can be found in various types of music, from classical to popular.

Sequences can be used to create tension, build momentum, or provide cohesion within a musical piece. They can also add interest and variation by introducing different motifs or themes throughout a composition.

In classical music, sequences are often used in the development section of a sonata form or in a fugue to explore different permutations of a theme. In popular music, sequences can be found in various forms, such as chord progressions, riffs, or melodic phrases that are repeated with slight variations.

Overall, sequences are an important compositional tool that can help structure and unify a piece of music, while also providing opportunities for creativity and innovation.
