Manners had worked since the late 1940’s with a collaborative group of scientists and medical doctors in researching the biosignatures of the human body. After decades of countless trial and error experiences, Manners and his group developed over 700 commutations to identify the precise combinations of frequencies associated with healthy tissue and organ systems.
Each commutation consists of five harmonic frequencies of audible sound that support the body in normalizing imbalances and synchronizing the cell’s frequency back to their natural healthy state of vibrational resonance.
While Manners and his colleagues were proceeding with their research, a Swiss medical doctor, Dr. Hans Jenny was conducting ‘cymatic’ (sound wave) experiments. Jenny coined the new term, “cymatics,” which comes from the Greek word—kyma, meaning ‘wave.’ Jenny’s experiments still fascinate audiences today. (see cymatic image on right). Due to his great respect for Dr. Jenny’s work, Manners named his sound therapy instruments “Cymatic Therapy” instruments.
Here’s a short video to show you some of the early research done by Dr. Hans Jenny
For decades, many traveled from around the world to experience Dr. Manners “Cymatic Therapy” at Bretforton Hall Clinic in the United Kingdom. During this fifty-year period, clinical research continued using sound, light and color therapy.
In 2005 Dr. Manners closed his clinic and retired to the English countryside with his wife, Doreen. Dr. Manners passed to the realms of celestial sound on August 21, 2009.*
Cymatics instruments have had numerous evolutions over the decades, including: Mark I, Mark III, Mark V, Mark VI, Cyma1000 and CymaLumiere; each generation utilizing the latest available in technology to build on the success of previous models.
Cyma Technologies International continues this research and development to constantly improve Cymatic Therapy instruments. See Products

A Pioneer in Sound Therapy
Dr. Peter Guy Manners
Departed August 21, 2009
Dr. Peter Guy Manners, a British osteopath, was qualified in England and Germany and specialized in natural and electromagnetic medicines.
Dr. Manners studied and collaborated with many outstanding scientists, including Dr. Hans Jenny (Switzerland) and Dr. Harold Saxon Burr of Yale University (U.S.). He researched the use of cymatics and biomagnetics for medical diagnosis and treatment, including the healing effects of certain sound vibrations and harmonics on the structure and chemistry of the human body as well as the importance of sound and light in our natural environment.
Dr. Manners was awarded the Dag Hammarskjold Merit of Excellence for benefits to humanity and Academie Diplomatique (De La Paix) as well as the Diploma of Honour in Bio-energetic Medicine (Moscow) for his contribution to research and development of bio-magnetic medicine.
Dr. Peter Guy Manners was a man who inspired many to delve into the limitless possibilities of energy medicine.
His contributions to healing with sound and color through vibrational technology have changed the world. He touched numerous lives informing the world of the work of Dr. Hans Jenny, Cymatics, Cymatic therapy and Cymatherapy. Because of him, the world is a better place.
This website is dedicated to Dr. Peter Guy Manners’s biography and contributions to the world of vibrational medicine. You may contribute to the blog and send his wife, Doreen a note of expression.
Many of us knew of Peter’s fondness of choral music; we can now hear him sing with the heavenly choirs!

Comments by Jonathan Goldman:
Dr. Peter Guy Manners was a great mentor of mine in the 1980’s. He knew more about the power of sound than anyone I had ever encountered. One of the true pioneers of Sound Healing, his understanding of the uses of sound to heal and transform led to the manifestation of Cyma-Therapy as well as many other applications of sound to create positive shift and change. He influenced and affected many. He will be dearly missed by those who knew him.

Comments by Steven Halpern:
” I met Dr. Peter Guy Manners when we were both speakers at the First Mind-Body-Spirit Festival in London, l977. I had read a brief summary of Dr. Jenny’s research, but had no idea that a)secret video existed, and b) the theories had been put into practice at Dr. Manners’ clinic. His presentation at the festival and the healing work at his clinic opened up new vistas and possibilities for the modern use of the healing powers of sound and music.
Inspired by my visit to the clinic and his writings, I featured the ‘sound evidence’ that cymatics provided in my first book and in all my lectures and workshops. I was honored to help spread the ‘good news’ that ‘there was more to sound healing than meets the ear” and to introduce his work to the American mainstream.
With deep appreciation,
Words from Chris Gibbs, the last UK student and assistant to Dr Peter Guy Manners
Dr Manners began his career in England as a young, ambitious doctor and researcher in the early part of the twentieth century. Even then, he knew that medical interventions were not providing complete solutions to resolve illness. This wisdom and a strong determination for change led him on a journey to various medical and research facilities across the UK and Eastern Europe, where he acquired and experienced many cutting-edge research and therapeutic interventions that pioneered the early use of sound as therapy. Working at his clinic, home and research centre in Bretforton Hall, UK, Dr. Manners encountered many personal challenges and acquired great knowledge which led to the invaluable conception in the early 1960s of one of the world’s first-known sound therapy instruments. This development marked the birth of what we now know as Cymatic Therapy or Cymatherapy ®®, which is the therapeutic application of sound and magnetic energy, based upon research from the field of Cymatics. Dr Manners tirelessly and single-handedly developed, promoted and taught Cymatic therapy throughout the world. His greatest achievement was that he generated and inspired so much interest in the therapeutic use of sound. One only has to look at the many international qualifications, awards, attended conferences, television appearances, and students that he has trained over the last five decades to appreciate his vital contributions to this field. In more recent times and several decades past the age of retirement until the closure of his clinic in 2005, Dr Manners tirelessly continued to teach, practice and promote Cymatic Therapy to people throughout the world. Since then, his loving and supportive wife, Lady Doreen Manners, and I assisted him in his home-based practice, and in organising the vast archives of material that he wrote and acquired throughout his career. Even during the months before entering a nursing home in May of this year, he was continuously organising and reviewing his work, so that we may all benefit from his infinitely valuable legacy. Dr Manners sadly went into decline after been struck down with illness in June, but he can now rest in the knowledge that he achieved all that he had wanted to with his many contributions. I had the great privilege of working with Dr Manners during the last 10 years. He was a tremendously dedicated mentor and teacher but, most of all, a dear friend who had the compassion to treat me like family.
Thanks to everyone for their kind words, tributes and collective support from all corners of the globe, since the passing of Dr Peter Guy Manners on Friday, August 21, 2009. I am certain that it would have given him tremendous joy and assuredness to know that his professional contributions and efforts have reached and inspired so many people throughout the world.
