Currently, researchers and practitioners are exploring the effect of sound on the body. In earlier times the music of the spheres was a popular concept introducing the idea that the motion of planets and other entities in the cosmos produce music at varying frequencies, which can be heard either consciously or unconsciously.
The harmonious rhythms of this music were said to influence human activity making babies smile when they hear the harmonic rhythms. The choreography of T’ai Chi Ch’uan is designed to be spherical, and energy created from the movement is referred to as Qi.
In 1994 a bio-recliner was being tested at the Human Performance Institute of the Loma Linda University Rehabilitation Center in California. The chair was designed to input music through sensors located at key places in the chair for interaction with the physical body. Varying styles of music would be played, and the reactions of a person in the chair were monitored and analyzed. At the Special Interest Group for Computer Graphics and Interactive Techniques (SIGGRAPH) Conference that year, an exhibit for The Edge Exhibition made the chair available for conference attendees. Additionally, a brainwave interface system was used to monitor brainwave frequencies, amplitudes, and coherence to analyze the brain’s responses to the music’s frequencies interacting with the body.
Brainwave music created by Paras Kaul is generated directly from the brain, input to MIDI instruments and sound software, and edited as music compositions, which are intended to demonstrate that the brain produces fast-moving, chaotic sound when producing predominantly beta frequencies and slower, ambient sound when signaling in predominantly low frequencies. Brainwave Morphing, her brainwave music album takes the listener through a series of tracks composed from a variety of brainwave states.
