Benny Goodman
Jazz clarinetist Benny Goodman, c. 1945.
In the context of swing music, a riff is a simple musical phrase that is reiterated by a band or a specific section of the orchestra. These phrases were used to shape the sound of the era in several key ways:1
- Structural Element: Riffs served as a foundational building block for compositions. When the Count Basie band reintroduced the riff, it became a widely adopted structural tool for the many orchestras that emerged during the swing era.2
- Antiphonal Interaction: Orchestras organized their players into sections of brass and woodwinds, often playing these sections off against one another. Riffs were frequently used in musical dialogue or counterpoint, where one section would riff against another.1
- Hypnotic Power: By repeating a riff with increasing intensity, bands could create a compelling, almost hypnotic momentum that defined the swing sound.1
- Support for Improvisation: Riffs provided a rhythmic and harmonic framework that supported soloists, allowing them to improvise over the steady, repetitive energy of the ensemble.23
By the late 1930s, riff-based tunes became a generic tenet of swing, helping to satisfy the massive demand for danceable jazz music.2
