 These are higher quantum frequencies. They have a specific purpose. Each note, each frequency has a specific purpose to stimulate the brain. So with it, you can play our frequencies, you can play the quantum frequencies, higher quantum frequencies, or write frequencies through the coil. So we have three levels of frequencies, and then there's inner circle. So there's four levels of frequencies, and those are the ones that you would use through the coil. And there, each frequency we have, I mean, there's 10,000 write frequencies, there's 6,800 quantum frequencies. Each one has been specifically programmed. Each one's, each quantum frequency takes about 60 days to make. So we're not just randomly selecting these tones, that we actually have to use a algorithm, use a geometric model, use brainwave sampling to, and then test, retest, give it to a small group of people, get the feedback and then retest it, and also convert it so that they sound good too. Because a lot of these frequencies that are beneficial for you don't necessarily sound that great when you play it, but we make sure that at the end of all the processing that we do, it actually sounds good to listen to too. So it's not music, it's like music, but it's based on mathematics, based on geometry, based on brainwave frequencies, based on psychotropic triggers that are known to make your brain stimulated, like to give you a altered consciousness experience.
