Ok work at a buisness and we build machines.

We put these in steel buildings and concrete buildings at altutude and below sealevel they shake around a lot.
we have a machine to test the machines and it gives vibration and sign wave and frequency pretty amazing bit of kit.

Any way there are magic frequencies when you build these things whether they are steel or concrete and dependent on the physical structure they all require a different frequency for differing structures so basically the same machine needs to have a different " heartbeat or rhythm " in one structure than another.

Found all this pretty interesting paticularly cause its work but also cause i like music and surfing like most civilised people.
this brought me to some of these magic frequencies like i was a sound pioneer.
Cymatic frequencies was part of this and i thought that there would be a dull and boring explanation and that would be a wrap.
What actually happened is i found some stuff that the sky fairies and science had a lot of explaining to do.

To be honest its amazing I urge all to have a look at cymatic frequencies and google up on it.

If you have any interest in sound moving obects ancient shapes tribal symbols music art science shamans and chants than have a good look. It was sort of like the first time i saw a david attenborouh movie. Big call i know but its some pretty interesting stuff.

Its real have a look
