La Carlotta

La Carlotta Giudicelli is the lead of many operas at the Opera Populaire, and is the prima donna.

La Carlotta is singing in her first appearance during the rehearsal, and two woman are silently complaining about her voice. She keeps returning to her dog, and has the same two women spraying a liquid into her mouth. She remarked "ha!" when the former manager announced that he was retiring, and when Raoul was introduced, she appeared to be especially interested in him. She threatens to leave, and when the new managers ask the former manager what to do, he shrugs and says "Grovel." So the two new managers tried flattering Carlotta into remaining, and she agrees, and goes to sing her aria, but a backdrop falls on her. This time she does leave, and Christine sings in her place. When Carlotta hears how the opera went that night, she fainted.

She appears the next day and is furious because she believes that Raoul sent a note (though it was really Erik who wrote it) warning her that her days at the Opera Populaire are numbered. The new managers convince her to remain and sing the lead role of countess at the next performance, though the Phantom wished for her to play the page boy because it was the silent role. In the dressing room, the new managers are showing different gifts, which she shows preference to a black poodle similar to the white poodle she already had. She is carried around that day, but when she sings as countess, the Phantom appears and Christine breaths, "It's him!" Carlotta snaps, "Your part is silent, little toad!" and continues to smile at the crowd. Erik remarks that perhaps it is Carlotta who is the toad, and he replaced the liquid that Carlotta sprays into her mouth when she sings with a liquid that kept her from singing. Carlotta had to run off the stage, and Christine once again took her place.

Carlotta then appears at the New Years Eve Masked Ball, and was one of the onlooking crowd when Erik appeared.

Carlotta takes part in the performance of Don Juan, the opera written by Erik. She cries over the body of Ubaldo Piangi on stage. That is the last we see of her.

Ubaldo Piangi
Carlotta often appears with Ubaldo Piangi, and they are lovers. When things go astray, he is the one she turns to for help, and she cries over his body when he was killed in the Don Juan Triumphant opera.

Christine Daae
Carlotta and Christine were rivals for playing the lead part in operas, and she believed that Christine was a threat to her place in the Opera Populaire.
