 Have you ever felt strangely drained after listening to music for a long time? What if I told you it's not just the music, but the tuning itself that could be affecting you?" So John and Mary were catching up over coffee. John, a health enthusiast, was sharing something fascinating he learned about sound frequencies. Mary, John said, there's this frequency called 528 Hz, and apparently it's the key to unlocking amazing health benefits. Mary raised an eyebrow. Really? Sounds too good to be true. John leaned forward. Well, it gets even weirder. Our current standard tuning, 440 Hz, might actually be harming us. They say it disrupts our brains and keeps us out of sync with the universe's natural frequencies. John explained that ancient musical scales had nine core frequencies, but some were purposely removed. The 528 Hz frequency, linked to the color green, is said to have powerful healing properties. Imagine, John said, like a radio station with bad reception. That's how we've been living with the wrong tuning.
