This Is What Earth’s Magnetic Field Sounds Like

The ancients believed that Earth was surrounded by celestial spheres, which produced divine music when they moved. We lived, so to speak, in a huge musical instrument.

> which produced divine music when they moved

Another mistranslation, I suspect. For “divine” read “astronomical”. For “music” read “harmony”.

In an infinite number of planets with infinite magnetic fields, could one produce Beethoven’s Fifth?

Whistlers, like lightning.

No! Whistlers are not resonances.

The whole thing, or just the first four notes?

Same answer anyway.

I don’t know. If it is possible then there will be an infinite number of planets amongst the infinite number of planets which do the first four notes, and also an infinite number that do the whole thing.

If it is not possible, then there will be zero.

I don’t see why not. Plasma waves in planetary magnetic fields are generally in the same frequency range as human hearing.

Or you could do what the astronomers and bat detectors do. Keep the same note and change the pitch it’s played at.

Some concert instruments would be more difficult to synthesise than others.

There are plenty of recordings of other planets magnetic fields as well.

This is Saturn. https://www.nasa.gov/wav/123163main_cas-skr1-112203.wav

This is Jupiter. https://youtu.be/8CT_txWEo5I?list=PLTiv_XWHnOZpM1iLQr95P4KDXYiYnJUOE
