I have to say this because it was such an unusual experience for me. Saturday night, I had trouble falling asleep. I found a YouTube link to the solfeggio frequencies. I never heard of them before Saturday, then today I came across 2 articles on these frequencies. well I fell asleep as they played. I woke in a half sleep state, but could feel electricity on my cheeks. it felt like small hairs, but immediately thought of electrici wires, well I couldn't tell if they were being pulled or penetrating the skin.

Tesla is known for the quote "If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe."

Solfeggio Frequencies

174 Hz = 1+7+4=12 1+2=3
285 Hz = 2+8+5=15 1+5=6
396 Hz = 3+9+6=18 1+8=9
417 Hz = 4+1+7=12 1+2=3
432 Hz = 4+3+2=9 9+0=9
528 Hz = 5+2+8=15 1+5=6
639 Hz = 6+3+9=18 1+8=9
741 Hz = 7+4+1=12 1+2=3
852 Hz = 8+5+2=15 1+5=6
963 Hz = 9+6+3=18 1+8=9

I had my pianos tuned to A=444Hz, which gives me access to the Solfeggio Frequencies.
