Hi there ... Welcome at Roel's World, thank you for visiting my blog, enjoy your stay!

  • 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.

  • Your pages on the history of people discovering and directionally amplifying cymatics is just great. Also the 432 underbelly of the investigation is so informative and refreshing.

  • 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
  • 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.
