In arts, the Baroque (or baroque) is both a period and the style that dominated it. Baroque style used exaggerated motion and clear, easily interpreted detail to produce drama, tension, exuberance, and grandeur from sculpture, painting, literature, and music. The style started around 1600 in Rome, Italy and spread to most of Europe. In music, the Baroque applies to the final period of dominance of imitative counterpoint.
(The name adapted a French adjective that is derived from the Portuguese noun "barroco"; both described a pearl of irregular shape. Some confusion can occur in using for the period and style the lower-cased version "baroque", which can instead mean merely "elaborate" [or especially "overly elaborate"] without implying connection to the period.)
The popularity and success of the "Baroque" was encouraged by the Roman Catholic Church when it decided that the drama of the Baroque artists' style could communicate religious themes in direct and emotional involvement. The secular aristocracy also saw the dramatic style of Baroque architecture and art as a means of impressing visitors and would-be competitors. Baroque palaces are built round an entrance sequence of courts, anterooms, grand staircases, and reception rooms of sequentially increasing magnificence. Many forms of art, music, architecture, and literature inspired each other in the "Baroque" cultural movement. Wikipedia
