Giacomo Puccini was an Italian composer whose operas, including La bohème, Tosca, Madama Butterfly, and Turandot, are among the most frequently performed in the standard repertoire. Some of his arias, such as "O mio babbino caro" from Gianni Schicchi, "Che gelida manina" from La bohème, and "Nessun dorma" from Turandot, have become part of popular culture.
