Inherent
in
the resources of
your organ
are the four basic families
of organ
tone:
string,
flute,
reed
and
diapason. All organ
voices
fall
into
one
of these four groups. The
flute tones are
mellow
with
very
little
overtone. String tones resemble
the string instruments of an
orchestra.
Reed
tones
have
vibrant,
penetrating
charaaeristics.
Diapason
is
the
basic
organ sound and
is
characterized by
full-
ness
and
richness of
tone.
Each
Control
is
in
itself
a solo voice
—
yet,
in combination, an
infinite
variety of
other solo voices
and
ensembles
is
produced.

The
six
black Solo
tablets (see
above
illustration) multiply
the dramatic
effects possible
on your
Wurlitzer Organ. These
controls
make
more
prominent any
selected tonality
or pitch
singly or
within
a combination.
For example,
if
you
feel
that the
volume
intensity of the melody
is
too
soft
and
should be
in-
creased, instead of adding
more
voices,
you
can
select
a solo control or two and
the melody
will
suddenly
stand out
like
a
solo
instrument
in
an
orchestra.
Also, the Solo Control
is
very
useful
in
another
way.
When
combinations
of voices are
in
use,
and
you want one
particular pitch
or tonality to stand out
above
the others, a
Solo Control
will do
this
for you.
The
16'
Solo Control will bring
out a
16' voice,
the 8' Solo
an
8'
voice, the
4'
Solo a
4'
voice,
and
so on.
SELECTIVE
VIBRATO
The
Vibrato,
as the
name
implies, causes the
organ
tone
to vibrate, or pulse, and
creates a
thrill-
ing
effect
of
warmth
and
beauty.
The
selective
Wurlitzer Vibrato
gives you
independent
control of
both speed and
depth
of vibrato
. . .
Speed
is
die frequency of
die
pulse
—
Depth
is
the amplitude
or
extent, of the
pulse.
'
The
three
Vibrato Controls
offer a variety of
effects
.
.
.
from
a delicate shimmering
quality
to
full theatrical throb. The
Vibrato (both Speed
and Depth)
is
"OFF"
unless
you
press
the lower
half of the
first
Vibrato Control
tablet to the
"ON"
position.
The
positions of the
next two
tablets
determine
the
degree of Vibrato Speed
and Depth
as
indicated on
the
tablets.
For your
favorite
hymns
and
other
church
or
classical music, you
will
find the 4100 Organ
tone excellent without
Vibrato.
The
popular
organist will use a great deal of vibrato
and
the
classical organist,
litde.
Your
4100 Organ
can provide
any
vibrato
effect for any
type of music.
Experiment with
the Vibrato
controls
to find
the
effects
you
like best
for the different types of
music you
play.
