Music therapy is a paramedical discipline that uses sound, the
music and movement to cause "regressive" effects and open channels of
communication with the aim of activating the socialization process. It's
therefore a psychotherapeutic technique to improve the quality of life,
rehabilitate
and recover, where it is possible. Using musical listening to heal and
prevent, among other things, nourish
literally the body with the sound and use the sound to discover the
dimensions hidden in the depths and to accelerate the process of evolution
of consciousness. We distinguish a phase of "hearing" sounds as a
peripheral bound phenomenon
to the ear, a phase of "feeling" that would be placed above all in the
thalassic functions, to get to "listen" to the music, with a
global involvement of our nervous system and psychic functions at
this connected.
In addition to emotion, music involves reactions on the listener
of the vegetative sphere: we are witnessing changes in blood pressure
heart rate, breathing, etc., but mostly even when the
music is perceived unconsciously.
Music should be considered on the one hand a non-verbal language, on the
other a
emotional communication medium. In the course of our daily life we all
experience
different "states of consciousness". For example, in the span of one
day, between the morning light and the dark of the night, we move
from an ordinary waking state to the different stages of sleep.
But even "extraordinary" states of consciousness are part of
our common experience: when we feel particularly
"creative", unusually "intuitive", exceptionally "lucid",
deeply "relaxed".
Ordinary, or extraordinary, all the stages of ours
consciousness are due to the incessant electrochemical activity of the
brain, which manifests itself
through "electromagnetic waves": brain waves, in fact.
The frequency of these waves, calculated in 'cycles per second', or Hertz
(Hz), varies depending on the
type of activity in which the brain is engaged and can be measured with
electronic apparatus. Scientists commonly divide these waves into "four
bands", which
correspond to four frequency bands and which reflect the different
"activities of the
brain".
Delta waves
They have a frequency between 0.5 and 4 Hz and are associated with the
deepest
psychophysical relaxation. The less frequent brain waves are
those of the unconscious mind, of dreamless sleep,
of total abandonment. In this sense they are produced during
unconscious processes of self-generation and self-healing.
Theta waves
Their frequency is between 4 and 8 Hz and they are proper to the mind
engaged in activities of imagination, visualization, inspiration
creative. They tend to be produced during deep meditation. The
dreams with open eyes, the REM phase of sleep (ie, when you dream).
In waking activities, theta waves are the sign of knowledge
intuitive and of an imaginative capacity rooted in the depths. Generally
they come
associated with creativity and artistic attitudes.
Alpha waves
They have a frequency ranging from 8 to 14 Hz and are associated with one
alert but relaxed state of consciousness. The mind, calm and receptive, is
focused on solving external problems, or on achieving
a light meditative state. Alpha waves dominate in moments
introspective, or in those where the concentration is most acute
achieve a specific goal. They are typical, for example, of the brain
activity of who
is engaged in a session of meditation, yoga, taiji.
Beta waves
They have a frequency ranging from 14 to 30 Hz and are associated with
normal waking activities, when we are focused on external stimuli.
The beta waves are in fact the basis of our fundamental activities of
survival, ordering, selection and evaluation of stimuli
that come from the world around us. For example, reading
these lines your brain is producing beta waves. They then allow us to
faster reaction and quick execution of actions. In moments of stress or
anxiety
beta give us the opportunity to keep the situation under control and give
a quick solution
to problems. In 1665 the Dutch physicist and mathematician Christiian
Huygens, among the first to postulate the
wave theory of light, observed that, by placing side by side and on the
same wall two
pendulums, these tended to tune their own oscillatory movement, almost
"they wanted to take the same rhythm". From his studies derives that
phenomenon that today
we call 'resonance'. In the case of the two pendulums, it is said that one
makes the other resound to the
own frequency. In the same way and by the same principle, if one strikes a
tuning fork, which produces waves at a fixed frequency of 440 Hz, and
places it near a
second tuning fork 'silent', after a short interval the second one also
begins
to vibrate. Resonance can also be used in the case of brain waves. Studies
that used the electroencephalogram showed a
clear correlation between the stimulus coming from the outside and the
brain waves of the
subject under examination. Initially, research in this field mainly used
the
light; then, we switched to sounds and electromagnetic stimulations. What
observed is that if the brain is subjected to impulses (visual, sonorous
or electric) of a
certain frequency, its natural tendency is to tune in. The phenomenon is
called 'frequency response'. For example, if a subject's brain activity is
in
beta wave band (therefore, in the waking state) and the subject is
subjected to a
certain period at a 10 Hz stimulus (alpha waves), his brain tends to
change his
activity in the direction of the received stimulus.
The subject then passes to a state of relaxation proper to alpha waves.
