Binaural Beats and Isochronic Tones
According to information in Wikipedia, "Solfeggio frequencies is a term coined by Leonard Horowitz and Joseph Puleo in 1999. It is a system of musical tuning for pitched instruments, referring to a belief that a set of nine frequencies derived from numerology were used centuries ago in Gregorian and Sanskrit chants. These frequencies are believed to create positive shifts to those in proximity to them. It is claimed that each frequency has specific spiritual and physical healing properties. It is also claimed that they are part of a process that can assist you in creating the possibility of life without stress, illness, and sickness". This website does not promote Solfeggio frequencies as an alternative to any medical problems. Please take a look at the Frequently Asked Questions page for clarification.
