How are lights in concerts and festivals synced so precisely to the music and the artist. My question regards both the mechanical lights and the human operated ones like spotlights.

Just like computer games.
Audio hardware at the concerts are connected to wide variety of tools such as equalisers. These tools can process and filter audio data to observe for a desired pattern/behaviour such as beat drops or volume levels. Then, they relay a data package to the light sensors. So when there’s a heavy bear drop, this is detected and the spotlight glows. If the volume is low, it rotates around slower. If there’s a guitar, the spotlight flashes in-between. Just giving out some examples 😅
These light sensors are preprogrammed before concerts to help artist to handle the show easily.
For manual controls, it’s the same but instead of an automated process, producers/artists do it manually with keypads/buttons/etc.
