Music of the Spheres

Beginning with our favorite sphere. . .
Earth's natural radio emissions that occur in the extremely-low-frequency to very-low-frequency
(ELF-VLF) radio spectrum. These emissions are vibrations of
electric and magnetic energy (electromagnetic waves) which cannot be heard without an audio-frequency ELF-VLF radio receiver. (Example is 81k .wav file)
