Cristina is a lady who loves to sing and make music. She's really good at it! People like to listen to her because her voice sounds nice and makes them happy or sometimes sad, depending on the song. Cristina also likes to write her own songs sometimes, which means she makes up the music and the words all by herself.

Either way, Cristina loves to share her music with the world and make people feel good.
