when constitute one Oh the greatest
contributions to the art OF tone produc-
ton that the pipe organ industry ever
has known. They likewise constitute
powerful selling force, giving the Estey
company something to tax about, IN
addition to the many other notable foa-
lures of their product which no other
concern possesses.
The object OF one or these latest IN
Ventions is to enable tones of low ptch
to be produced by shorter pipes than
heretofore have been necessary From
the earliest period in the history of or
gan pipes it has been well known that
increasing the length of the pipe lowered
the pitch and that tone of the octave
below given note involved pipe nay
ing double the speaking length. This
acoustic law has necessitated the use of
very long pipes i'm order to produce notes
of low pitch. In most organs open
pipes giving a 16-foot tone are employed
involving a speaking length of approx
mately 16 feet. There are many situa-
TONS however, in which it is desired to
use pipe organs in which there is not
available room for pipes of such length,
and the fact applies with still more force
where it Is desire0 to use 32-foot pipes.
