Music
is
an
important
part
of
our
lives
.
We
connect
and
interact
with
it
____________________
and
use
it
as
a
way
of
projecting
our
____________________
-
identities
to
the
people
around
us
.
The
music
we
enjoy
?
whether
it's
country
or
classical
,
rock
n'
roll
or
rap
?
____________________
who
we
are
.
But
where
did
music
,
at
its
core
,
first
come
from
?
It's
a
puzzling
question
that
may
not
____________________
a
definitive
answer
.
One
____________________
researcher
,
however
,
has
proposed
that
the
key
to
understanding
the
origin
of
music
is
____________________
snugly
in
the
loving
bond
between
mother
and
child
.
In
a
lecture
at
the
University
of
Melbourne
,
Richard
Parncutt
,
an
Australian
-
born
professor
of
systematic
musicology
,
endorsed
the
idea
that
music
originally
____________________
from
'motherese'
?
the
playful
voices
mothers
____________________
when
speaking
to
____________________
and
____________________
.
As
the
theory
goes
,
increased
human
brain
sizes
caused
by
evolutionary
changes
occurring
between
one
and
2
,
000
,
000
years
ago
resulted
in
earlier
births
,
more
fragile
infants
and
a
____________________
need
for
stronger
relationships
between
mothers
and
their
____________________
babies
.
According
to
Parncutt
,
who
is
based
at
the
University
of
Graz
in
Austria
,
?
motherese'
arose
as
a
way
to
strengthen
this
____________________
bond
and
to
help
____________________
an
infant's
survival
.
