Final answer:
A concerto grosso and a symphony are two different forms of musical composition. A concerto grosso consists of a small group of soloists and a larger ensemble.
Step-by-step explanation:
A concerto grosso and a symphony are two different forms of musical composition that evolved during the Baroque and Classical periods, respectively. A concerto grosso consists of a small group of soloists and a larger ensemble playing in alternation.
In contrast, a symphony is a purely orchestral composition that typically consists of four movements and is written for a full orchestra.
One key difference between the two forms is the role of the soloists. In a concerto grosso, the soloists play a prominent role and often engage in musical dialogue with the larger ensemble.
In a symphony, however, there are no individual soloists; instead, the entire orchestra works together as a unified ensemble. Another difference is the structure and overall character of the composition. Concerto grossos are typically more virtuosic and flashy.
With a greater emphasis on the individual skill of the soloists. Symphonies, on the other hand, are more symmetrical and balanced in their structure, with each movement serving a specific purpose within the overall composition.
