Classical era music is a style of Western music composed from approximately 1750 to 1820, with the period falling between the Baroque and the Romantic ages.
In the middle of the 18th century, Europe began to move toward a new style in architecture, literature, and the arts, generally known as Classicism, and this sought to emulate the ideals of Classical antiquity and especially those of Classical Greece. The new classical music style had a lighter, clearer texture than Baroque music and was less complex. The typical orchestra size also increased.
The new style was also pushed forward by changes in the economic order and in social structure. As the 18th century progressed, the nobility became the primary patrons of instrumental music, and this led to changes in the way music was performed. Forms such as the concerto and sonata were more heavily defined and given more specific rules, and the symphony was created in this period.
