PERCUSSIONS-Typical
percussion \oiees
on

organ include the Harp, Carillon and Chimes ,md often.
on
electronic organs, the Harpsichord and Piano,
The
Piano
is
used
to providc the percussive sounds orten called for
in
contemporary organ literature. while the Harpsichord
is

for

PIPE-The
metal or
wood
single note windblown tone produ
c-
ing device that is the basis for pipe organ sound,
The
two
basiC
types are the flue pipe and the
reed
pip
e.
Each pipe
is
its
own pitch generator, tOile gen erato
r,
and audio
system.
PIPE AU(;MENTATION-The combining
of
windblown pipes
with electronic voices to create a combination instrument
with the main prineipal and flute choruses coming from
real pipes and supplementary voices being genera ted

the addition
of
pipes

installation or
at
a future date.

They
arc
located
on
the piston rails below each keyboard , These
pistons are also
used
to access special microprocessor
test and
voicing
programs
built
into
each Rodgers
console.
PRINCIPALS-The
tonal family unique to the organ that has
no
orchestral counterpart.
The
Principal Chorus (8: 4: 2')
is
the
bas

Also
sometimes called the Diapason.

PRESETS-See "Combination Action," number
1.
Preset
sys-
tems are
no
longer
used
on
Rodgers organs.
RANK-In
pipe terminology, a rank
is
defined
as
a set
of
pip
es
possessing a uniform tone quality, one pipe for each note
on
the keyboard. A rank,
in
electronic organs,
is
ncarly
impossible to define, due to the multiple sounds available
from a single tone generator.
REED-One
of the two classes
of
organ stops, A
reed
pipe
generates
its
tone by the
vibration
of
a brass tongue
against a rectangular
op
ening, the resulting tone being
given security
of
pitch and timbre
by
a resonator placed
on
the
reed
assembly.
Reeds
arc the most colorful organ
family. They are
used
in
choruses and
as
solo stops,
REGISTRATION-Choosing and combining stops to play a
given
piec
e
of
music.
The
art
of
combining the sounds
of
an
organ
in
a given room to properly enhance the music
being played.
REGULATION-A
voicing procedure
in
which
each
notc of
each
stop
is
adjusted to assurc its proper relation to the
other notes of the stop
Clnd
that stop's relation to the rest
of the organ.
REGULATOR-An
air
regulation device
used
to maintain
even
pressure within the pipe chest. This
may
be a separate
device located betw
ee
n the blower ,md chest, or
built
into
the
chest.

in

SCALING-The
modification
of
the
harmonic
structure
throughout the compass of an individual
voice,
Rodgers
electron ic organ voices arc scaled
in
imitation of organ
pipes. Uniform harmonic structures,
as
in overall filter
systems or
digital
tone systems, are less
ex
pensive to
build, but are lifeless
and
musically uninteresting
in
com-
parison to a properly scaled
voi

SCHWIMMER-A
builL-in air r
eg
ulator system
used
in
many
Rodgers pipe chests.
SET
BUTTON-The
piston
that
is
pressed before pressing the
piston
on
which a combination
is
to
be
set. This applies
only to Capture Action.
SHARPS-The
typically black
keys
of
manuals and pedal-
boards.
On
Rodgers wooden-core keyboards, manual
sharps are made
of
real ebony or rosewood
(a
nice varia-
tion
to
the more common black).
SOLO
COUPLER-A
special Rodgers microprocessor device
that allows any stop or coupler of the Swell organ to
so
und
from the highest
key
played
on
the Great manual.
Thus,
a
solo and accompanime
nt
can
be
played from the
same
manual.
The
Solo Coupler
can
be
used
with the Continuo
to give the effect
of
two manuals and pedal all played from
the Great keyboard.
SOSTENUTO-
The
Sost.enuto allows a chord to
be
sustained
without holding the
keys
down.
Its
us
e
is
called for fre-
quently
in
piano tran
sc
riptions of orchestral accompani-
ments for choral works.
It
is
also
us
eful to sustain a chord
when
making registration changes or changing pages of
music.
STOP-Strictly
speaking, a stop
is
a chromatic series of tones
of like tone quality,
one
tone for each
key
on
the keyboard.
In practice, a distinction is made between speaking stops
