Giuseppe Saverio Raffaele Mercadante was an Italian composer, particularly of operas. While Mercadante may not have retained the international celebrity of Gaetano Donizetti or Gioachino Rossini beyond his own lifetime, he composed as prolifically as either and his development of operatic structures, melodic styles and orchestration contributed significantly to the foundations upon which Giuseppe Verdi built his dramatic technique.

Giuseppe Fortunino Francesco Verdi was an Italian composer best known for his operas. He was born near Busseto to a provincial family of moderate means, receiving a musical education with the help of a local patron, Antonio Barezzi. Verdi came to dominate the Italian opera scene after the era of Gioachino Rossini, Vincenzo Bellini, and Gaetano Donizetti, whose works significantly influenced him.
