 Good example there of a concerto grosso. Sometimes you heard the strings playing alone as soloists, and then they would simply blend in with the body of the orchestra, which is exactly how a concerto grosso works. As I mentioned before, mostly a Baroque form. Here is the concerto grosso No. 1 of the 12 by Charles Avison, based on the sonatas of Domenico Scarlatti. It's performed by the Berlin Ensemble. ¶¶
