neoclassicism

noun

• the revival of a classical style or treatment in art, literature, architecture, or music.

  As an aesthetic and artistic style this originated in Rome in the mid 18th century, combining a reaction against the late baroque and rococo with a new interest in antiquity. In music, the term refers to a return by composers of the early 20th century to the forms and styles of the 17th and 18th centuries, as a reaction against 19th-century romanticism
