In House M.D., what is the name of House’s fictional piano composition?

House’s fictional piano composition in House M.D. is called “Cuddy’s Serenade.”

The piece is associated with Gregory House’s musical ability and with his complicated relationship with Lisa Cuddy, the hospital administrator. House plays piano as one of the character’s recurring private activities, alongside guitar and occasional performances on other instruments. Music provides a glimpse of his concentration, wit, and emotional life outside diagnosis.

The title is a character-based reference rather than the name of a famous classical work. Cuddy is the fictional dean of medicine and hospital administrator whose professional arguments with House become a major part of the series. Their personal relationship later becomes an important storyline.

This fact is easy to confuse with the show’s many licensed songs and soundtrack cues. “Cuddy’s Serenade” refers to a composition within the fiction of House M.D., not to the series theme or to a commercially released song by the cast. The title’s possessive form identifies Cuddy as its subject.
