An individual member of the ripieno is called a ripienista. This is followed by another dialogue between soloist and ripieno based on the ritornello material. The harpsichord is both a concertino and a ripieno instrument. The middle movement is performed by the concertino without the ripieno instruments. Further, the concertino does not share thematic material with the ripieno, but presents unique ideas. In a ripieno concerto, there is no dominant soloist, so it resembles an early symphony. The ripieno ("tutti") plays the main ritornello theme, while soloists play the intervening episodes.
