Classical style is clear, complex, and distinct. It is marked by great variety and contrast in mood, flexibility in rhythm and texture, tuneful melodies set to sophisticated themes, and sophisticated use of dynamics. This period saw a decreased use of improvisation, since much of the work was written with amateurs in mind, who were not expected to master the art of improvisation.

A standardized orchestra evolved during this period, consisting usually of string, woodwind and brass sections. The typical form of composition for this type of orchestra was a four-movement piece, written for symphony, string quartet or sonata. Resources in this section provide information not only on classical music in Europe, but also the "classical" music of non-western countries.
