For Christopher Nolan's 'Interstellar,' composer Hans Zimmer made the bold choice to make a pipe organ the 'main character' of the score. Recorded at Temple Church in London, the organ was chosen because it is an instrument powered by air—symbolizing the 'breath' of the astronauts in their suits. Zimmer wanted a sound that felt more 'human' and 'technological' than standard synthesizers. The massive scale of the organ, with its towering pipes, provided a religious awe to the film's cosmic themes. During the film's most legendary sequences, the organ's volume literally vibrates the air in the cinema, making the audience feel the power of the black hole. This use of the 'King of Instruments' to score a journey into the unknown created a new musical legend in modern cinema history.
