After his studies, he worked as both a conductor and composer, beginning his professional journey in music. His background helped shape his future career in opera. Apart from "Cavalleria Rusticana," Mascagni wrote other operas like "L'Amico Fritz," "Iris," and "Isabeau." Although these operas were not as popular as his first, they are still performed and recorded today. Mascagni also conducted performances of his works and those by other composers throughout his life. He received several awards such as the Order of the Crown of Italy and the Grand Cross of the Order of Saints Maurice and Lazarus.
