What are harmonic entities?

Harmonic entities are things that vibrate together in a special way, like when you play music on your toy xylophone.

Imagine you have two bells, one is small and light, the other is big and heavy. If you hit both at just the right time, they will ring in a pattern that feels smooth and connected. That’s what harmonic entities do, they vibrate together so their sounds or movements match up in a pleasing rhythm.

Think of it like when you and your friend are jumping rope together. If you both jump at the same time, the rope moves smoothly. But if one of you jumps faster than the other, it gets bumpy. Harmonic entities are like friends who always jump in sync, they match each other's rhythm perfectly.

Harmonic entities follow a special rule: their vibrations happen at whole number multiples of each other. So if one thing vibrates 2 times every second, another might vibrate 4 or 6 times every second, always keeping that neat, musical connection.
