The quote 'Mankind was born on Earth. It was never meant to die here' defines the scope of 'Interstellar.' While the pipe organ is the star, Hans Zimmer also used the Hammond Organ for specific textures. Unlike the air-driven pipe organ, the Hammond is an electric organ that uses rotating tonewheels to generate sound. Zimmer utilized its unique 'Leslie speaker' (a rotating speaker cabinet) to create a sense of spinning and disorientation, mirroring the docking sequence in space. This blend of the sacred (pipe organ) and the mechanical (Hammond) created a legendary atmosphere of both hope and physics-defying tension. The Hammond's ability to 'growl' provided a modern grit to the film's celestial legend. This showed how different versions of the same instrument class can be used to contrast the human and the cosmic elements of a movie's quotes.
