Respuesta :
A baroque form that is described by the alternation of orchestra and soloist is called the ritornello form.
A ritornello is a repeated section in Baroque music for chorus or orchestra.
Ritornello form is a common structure seen in Baroque concertos. The ritornello, which translates to "the small thing that returns," is a repeating musical piece that alternates with freer episodes in this style. Ritornellos first appeared in trecento Italian madrigals, including those written by Jacopo da Bologna.
The first movement of Bach's Brandenburg Concerto No. 4 in G is a prime example of the Ritornello form. In this instance, Bach makes use of the structure by making the ritornello sections tutti while the episodes include solos from the concertino, which is made up of two recorders and a violin.
Aspects of Baroque traditions in the seventeenth century were a spectacle, movement, illusion, and biblical genre painting.
