Sound and Trance Formation

Sonund TransFormation

Here we present this training cycle in music therapy and therapy for altered states of consciousness, for personal, professional, and spiritual development. This course consists of 3 blocks of two weekends of theoretical and practical work. However, optionally, the course can be extended with the construction of an instrument. It is granted for therapists in general (psychologists, music therapists, psychotherapists, sociotherapists, and art therapists), and people who are seeking a broader and more spiritual approach in their own work within the context of therapies. It can also be a good complement for musicians, artists, coaches, etc.

The Team

Joel Olivé, music therapist, luthier, and musician

Dr. Peter Hess, psychiatrist, neurologist, music therapist.

Heike Hess, holistic therapist, sound therapist

The course "Sound TransFormation" (Sound and Trance States Formation) is based on 38 years of experience and development in psychotherapy, psychiatry, and music therapy. Peter Hess has created this new form of receptive music therapy, the renowned Gong Therapy. This is very similar to psychedelic therapy developed by Stanislav Grof and Richard Yensen and shamanic rituals, but has the advantage that these experiences can be more effectively integrated into our culture and society. The archaic instruments in the sound journey create a connection with the roots of our existence in the womb, but also in the roots of humanity as a whole. This allows us to go beyond duality and projects us towards a new model of consciousness through a conscious knowledge of the internal process.

The course offers practical and theoretical aspects, such as self-exploration through sound journey, bodywork, vibrational healing and body awareness, shamanic ritual in modern psychotherapy, musical improvisation with all kinds of instruments, active/receptive music therapy, introduction to interpretation techniques of archaic instruments and understanding their effects, harmonic singing, mindfulness and sound meditation, the theoretical background of the Gong Ritual, set and setting, the difference between active and receptive music therapy, the bridge between psychotherapy and shamanism, altered states of consciousness and neurology, spirituality in treatment, basic perinatal matrices according to S. Grof and transpersonal psychology.
