We
now
know

and
that
these
can
be
seen
by
the
eye
as
waveforms.
But
we
have
been
talking
about
‘‘sound”’
in
general
up
to
now
without
taking
into
consideration
that
there
are
high
sounds
and
low
sounds,
!oud
sounds
and
quiet
sounds,
mellow
sounds
and
sharp
sounds
...
that
is
to
say
a
great
variety
of
sounds
which
we
perceive
very
differently.
In
general,
sounds
can
be
classified
according

“volume”
and
“tone

which
are
called
the
“three

of
sound”.
In
other

sounds
are
determined
by
these three
basic
elements.
a

The
“three

of
sound”
are
“pitch”,
“volume”
and
‘‘tone
quality”.

We
can
now
have
a
look
at
how
these
three
basic
elements
are
connected
with
the
various
waveforms.
