Hello there, I'm Agent Of Solfeggio. This channel was made to provide music in any Solfeggio frequency.

What are Solfeggio frequencies?
Solfeggio Frequencies are typically used for transformational purposes and can help improve relationships, deal with fear and change, awaken one's intuition, etc.

The unique tones are found to impart spiritual blessings when they are played harmoniously. Every solfeggio tone comprises frequencies necessary for balancing energy, keeping the spirit, mind, and body in a perfect form of harmony.

Here are some examples of solfeggio frequencies available on the channel: 174hz, 411Hz, 528hz, 771Hz, 963hz etc. I can do any frequency within the frequency response for headphones of 20Hz - 20000Hz. I don't know why you'd want to go up 20000hz but it is possible!
