Giovanni Battista Bononcini was an Italian Baroque composer born in Modena in 1670 who began his career in Italy and later held posts and produced operas for courts and public theatres in cities such as Vienna and London. His output, which included operas, cantatas and sacred works, exemplifies an Italianate melodic style of the late seventeenth and early eighteenth centuries and his international career helped disseminate that style across European operatic circles.
