What is Orchestral music?
Orchestral music is a type of classical music that is written for and performed by an orchestra. The term usually refers to compositions in the Classical and Romantic periods. Most of the orchestral repertoire is written for the string section, woodwinds, brass, and percussion, with keyboard instruments (piano and harpsichord) used to fill out the harmonic spectrum. The orchestra has its roots in Baroque chamber music and Italian opera.
