The melody comes from Titanic, the 1997 film whose love theme became one of the most recognisable tunes in popular culture. Short, reworked versions of famous melodies have long circulated on soundboards and in short-form video, where a familiar tune can set up an expectation in just a few seconds. This flute version leans into that familiarity by sounding deliberately amateur, so the joke is clear even without dialogue. It remains useful because the Titanic theme still signals instant romance and drama, making a flawed performance an easy shorthand for parody.
