believed
that
music
originated
at
the
time
of
modifying
vocal
intonations
in
different
languages
.

Operation
of
sounds
:
Musical
sounds
are
produced
by
some
physical
processes
such
as
a
vibrating
string
,
the
air
inside
a
wind
instrument
,
etc
.
The
most
fundamental
characteristic
of
these
sounds
is
their
"
elevation
"
or
"
height
"
,
or
the
number
of
times
it
vibrates
per
second
,
that
is
,
their
frequency
.

137
subjects
were
chosen
for
the
study
.
Among
them
,
31
were
men
and
106
women
.
The
average
age
was
20
and
they
were
all
psychology
students
.
First
they
were
given
a
test
to
measure
their
state
of
anxiety
.
Afterwards
they
were
made
to
listen
to
fragments
of
heavy
metal
of
5
minutes
each
.
In
total
,
each
respondent
completed
a
47
-
minute
listen
.
The
researcher
was
able
to
observe
that
during
the
listening
lapses
,
the
participants
increased
nervousness
.
They
were
restless
and
expressed
this
by
constantly
changing
position
and
with
erratic
movements
of
their
hands
and
feet
.
Valderrama
was
able
to
conclude
that
this
type
of
exciting
melodies
increased
the
level
of
anxiety
.
The
explanation
is
that
this
kind
of
rhythm
intensely
stimulates
the
sympathetic
system
and
this
increases
physical
and
psychological
tension
.
If
this
is
not
released
through
movements
such
as
dancing
or
jumping
,
the
energy
accumulates
and
gives
rise
to
symptoms
of
anxiety
.
