overture (sh) and chi structure (medicine)


overture (sh)




Musical introduction to a larger, often dramatic, work.

Originating with Claudio Monteverdi's Orfeo (1607), overtures served as openings for operas. The large-scale two-or three-part "French overture" invented by Jean-Baptiste Lully (1658) for his operas and ballets was widely imitated for a century. The sinfonia, the standard Italian overture form in the late 17th and 18th centuries, was a principal precursor of the three-part sonata form and thus provided the model for the earliest symphonies, which consisted of three movements. In the 19th century, overtures independent of any larger work usually illustrated a literary or historical theme (see symphonic poem). Overtures to operettas and musicals have traditionally been medleys of their themes.
