I seal the Input of Spirit, with the Spectral Tone of Liberation.
I am Guided by my own Power Doubled."

  • Hey man, this is an amazing ressource for us musicians who are trying to make new records in 432hz.

  • Hello, I have recently found you in my search for evidence concerning 528 mhz and 7.83hz claims. Thank You again for your brilliant knowledge sharing!

  • Thank you for your very thorough report on the Sonic Geometry video!

  • I must thank you for all your work, it is nice to see someone who thinks this stuff is important, but also that it should be something all musicians can understand, not just professors and mathematicians.

    Tom Bobson
  • I'm going to go ahead and say… you are the man!!

    Todd Bartolomeo
  • I was searching for articles on music and the brain to read during breakfast when I found your website. Great stuff!

    Joe Brown
  • Thanks for your thoughtful and thorough debunking of Solfeggio. It should happen to more new-agey pseudoscience. Then, really finding out what might be going on in newly explored territory might be easier.

    Dameon Keller

  • Hello. Thanks for your wonderful article about Maria Renold and 12-true-fifths.

  • Hi Roel, your blog is very good and your thinking very clear. I've found on the internet many myths about 432 and 256. You expose them as myth, and it is very good, because mixing truth with false statements is dangerous for very good ideas.
