Resonance
is
the
vibration
of
sound
that
we
use
to
amplify
our
voice.
If
our
voice
were
a
HiFi-‐speaker,
then
our
body
is
the
speaker
box
which
allows
the
sound
to
vibrate
and
maximise
itself.
Just
like
the
speaker,
the
sound
created
initially
by
our
vocal
folds
is
really
very
tiny,
and
we
need
to
use
all
available
cavities
within
our
body
to
amplify
that
sound.
The
largest
cavity
is
the
lungs,
followed
by
the
mouth
and
nose,
and
then
there
are
hundreds
of
tiny
spaces
where
the
tissues
of
the
body
are
also
able
to
resonate
(head,
neck,
cheek
bones,
almost
everywhere).
The
construction
of
a
HiFi-‐speaker
box
will
also
affect
the
sound
it
gives
out,
depending
on
the
capacity,
and
the
type
of
materials
used
to
make
it.
Similarly,
the
choice
of
which
areas
of
our
body
we
resonate,
and
how
we
allow
vibrations
of
sound
to
travel
around
the
body,
will
affect
the
characteristics
of
our
singing
sound.
For
instance,
if
we
tense
muscles
in
our
neck,
we
make
the
muscle
tissue
denser,
and
vibrations
of
sound
can’t
then
pass
so
easily
from
the
chest
area
to
the
head.
This
is
why
we
need
to
stay
relaxed
when
we
sing!
