It was a popular convention of Italian and French opera in the early decades of the nineteenth century. Mad scenes were often created as a way to offer star singers a chance to show off their abilities, though many of them are also very dramatic. The vocal writing is often exciting and highly demanding, requiring immense skill." ] ,
