Energization
At the end of the 1940s, during his first experiments on
audio-vocal counter-reactions, Tomatis had observed unusual
changes in the behavioural dynamic of singers and actors.
According to the sound frequency zone
which was imposed on them auditorily, the latter became more
dynamic, adopted a more upright posture, began to breathe deeply
and to speak or sing with a lot more ease; or on the contrary,
slouched and quickly entered into a kind of torpor which they had
difficulty pulling out of.
The latter state, characterised by an
obvious loss of energy, deprived them of any possibility of
producing a quality vocal emission, whether for singing or
speaking, or even the desire to do so.
Only the frequencies corresponding to
the zone of high-pitched sounds established the first category of
reaction, of the dynamic type.
On the contrary, the low-pitched
sounds, deprived as they were of high-pitched frequential
components, systematically entailed the opposite reactions
characterised by an increase in fatigue.
These results were subsequently repeated thousands of times, not
only on singers and actors, but more generally on anyone
undertaking a course of therapy under the electronic ear.
Moreover, due to the fact well established by Tomatis that the
voice can only reproduce what the ear can hear and more
particularly what it accepts to hear (first Tomatis law), by
inducing people to favour the perception of high-pitched sounds
they are consequently capable of permanently re-energizing
themselves through their own voices. The voice can thus become the
medium for the permanent regeneration of its own dynamic.
Indeed, sounds which
are rich in high-pitched harmonics have the effect of stimulating a
vast nervous network called the 'reticular formation', which
controls the overall level of cerebral activity. This part of the
brain is strongly involved in the mechanisms of alertness, vigilance
and sustained attention. This is why these sounds will exert a
dynamogenic action, while favouring the triggering of these
mechanisms. They play a considerable role in the increase of
activity in our cerebral cortex, participating in the efficiency of
a high number important of processes involved in memory,
concentration and learning.
One can then
understand the benefit of a procedure aimed at educating or
re-educating the ear to sufficiently perceive the high harmonic
components of the sound messages which reach it. Consequently, any
given sound can become an endless source of energization, provided
it undergoes a phenomenon of appropriate filtering by the ear which
consists in minimising the impact of its low-pitched components
which offer little regeneration and even tire, while emphasising the
high-pitched parts, which are sources of invigorating stimulation.
While improving the
general state of the cerebral dynamic, a procedure of this
kind thus enables any person prone to fatigue or depression to
durably regain his or her full functional potential.
