the origins of the concerto can be found in
Concerto The concerto, as understood in this modern way, arose in the Baroque period, in parallel to the concerto grosso, which contrasted a small group of instruments called a concertino with the rest of the orchestra, called the ripieno. The popularity of the concerto grosso form declined after the Baroque period, and the genre was not revived until the 20th century. The solo concerto, however, has remained a vital musical force from its inception to this day.
