The origin of the concept of the ‘music of the spheres’ is attributed to ancient philosophers. It was based on an Earth-centered Solar System. The distance from the Earth of each orbiting celestial body had a tone, rather like the pitch of a note from a plucked string is related to the length of the string. In the 16th century, Johannes Kepler developed the idea for a Sun-centered cosmos. In the theory of the ‘music of the spheres’, the sounds are not supposed to be directly audible to mortals.
I wonder what the ancients – or indeed Kepler – would have thought of the comet's song. We are privileged mortals for we can hear it when the frequency is changed.
