Ripieno

In music, "ripieno" (Italian for "stuffing" or "filling") refers to the body of instruments accompanying the concertino (the small group of soloists) in a concerto grosso. The ripieno section generally provides harmonic support and rhythmic drive, contrasting with the more virtuosic and melodic passages played by the concertino. The term can also refer to the larger ensemble within a piece that alternates with smaller solo sections, even if the overall form is not strictly a concerto grosso. Essentially, the ripieno constitutes the "orchestral" or "tutti" sections of the piece, providing a fuller sound and contrasting texture. The size and instrumentation of the ripieno can vary depending on the specific composition and composer.
