Wendy Young, M.Mus, has music degrees from New York University and the New England Conservatory of Music. Since 1997, she has been on the music faculty at Princeton University, where she teaches harpsichord, and 17th and 18th century Baroque keyboard performance practices.

In addition, Wendy has appeared at numerous festivals including the Boston Early Music, Waterloo, Pepsico Summerfare, Oregon Bach and Marlboro Music Festivals and in Europe, at Vaison-la-Romaine (France) and Spoleto (Italy).

Always striving to stretch the limits of the harpsichord, her playing can also be heard on a recording with the the Art Farmer Trio playing jazz versions of the Bach Brandenburg Concerti, and numerous commercials and movie soundtracks, including the soundtrack for the Warner Bros. movie Interview with the Vampire.

In addition to her classical background, Wendy has been studying, teaching, and practicing the healing effects of sound, music, and vibration for over 30 years, and has worked with many of the leaders in the field. While she loves and uses many modalities, including Cymatherapy and Guided Imagery and Music, her particular specialties are Himalayan Singing Bowls and sound meditation. She is the director of the Princeton Sound School, and was the Program Facilitator/Mentor for the New York Open Center’s Sound and Music Institute, a 9-month certification program in therapeutic sound and music, from 2011 – 2015. Along with Mandara Cromwell and Stephanie Rooker, Wendy helped to create ISTA’s first Integrative Sound Therapy Practitioner Certification program. She is also writing a curriculum for Princeton University’s first ever undergraduate class on the effects of sound and music on emotions and the physical body.

Ordained as an Interfaith Minister through One Spirit Interfaith Seminary, and formally trained as a chaplain, Wendy offers spiritual counseling for individuals, couples, and groups. Her unique style of counseling combines the use of verbal and non-verbal therapies, including mandala work, singing bowls, and music.

Mandara Cromwell is the Founder and Board Chair for ISTA (The International Sound Therapy Association), producer of Cymatics~The Science of Sound and Vibrational Healing Annual Conference, CEO and President of Cyma Technologies, Inc., and 2013 Nominee for the Thomas Edison Award for Innovation in the fields of Science and Medicine for the AMI750®.

Experiencing a love for Gregorian chant as a child, Mandara continued on her sound journey after college, traveling to India to study Sanskrit chant, yoga, Ayurveda and meditation. Years later she was introduced to the world of Cymatics with the meeting of Dr. Peter Guy Manners, a British osteopath who discovered audible soundwave frequency patterns that effect cellular regeneration. Manners worked in collaboration with a group of scientists and medical doctors, for decades, formulating biosignatures and healing frequencies for each part and function of the body.  These “Cymatic Signatures” create cellular symphonies that nurture and nourish our body, mind and spirit, resulting in a state of harmonious health. Since Manners passing in 2009, Cyma Technologies continues the research and development of therapeutic sound devices implementing therapeutic audible frequencies.

Mandara Cromwell lectures on behalf of the International Sound Therapy Association—an organization dedicated to increasing the public’s awareness of the power of our thoughts and words, and sound in our environment.  ISTA is also dedicated to promoting therapeutic sound modalities to the healing world.
