The Entrainment Transformation Principle
A physics phenomenon of resonance, first observed in the 17th century, has an effect on all of us. Entrainment is defined as the tendency for two oscillating bodies to lock into phase so that they vibrate in harmony. It is also defined as a synchronization of two or more rhythmic cycles. The principle of entrainment is universal, appearing in chemistry, pharmacology, biology, medicine, psychology, sociology, astronomy, architecture and more. The classic example shows individual pulsing heart muscle cells. When they are brought close together, they begin pulsing in synchrony. Another example of the entrainment effect is women who live in the same household often find that their menstrual cycles will coincide.
Discovery of Entrainment.
The history of entrainment is linked to Dutch scientist, Christian Huygens in 1665. While working on the design of the pendulum clock, Huygens found that when he placed two of them on a wall near each other and swung the pendulums at different rates, they would eventually end up swinging in at the same rate. This is due to their mutual influence on one another.
Musical Entrainment.
The entrainment process is quite evident in music. It is possible to have rhythmic entrainment, melodic entrainment and dynamic entrainment. Entrainment music has the potential to (1) resonate with the listener’s feelings, (2) transform negativity into positivity, and (3) promote a state of liveliness or serenity. Certain sounds, in specific sequence can help bring the listener from one place to another. This process is also known as the “isoprinciple.”
The special music from Sound Feelings has been developed with the entrainment transformation principle in mind. It creates a type of sound “mirror” that first reflects the current stress or turmoil of the listener, and later reflects the desired mood and feeling. As the music gradually transforms, its resolution may be experienced in the listener, physically or emotionally.
