"Irene Adler's Theme" is a piece of soundtrack music composed by Michael Price and David Arnold for the BBC television series "Sherlock". It is associated with the character Irene Adler, a brilliant and enigmatic dominatrix who outwits Sherlock Holmes in the episode "A Scandal in Belgravia". The theme is characterized by its slow, melancholic, and seductive piano melody, often accompanied by strings, which captures Adler's intelligence, mystery, and the complex, charged relationship she has with Sherlock.
