THE MUSICAL RESOURCES OF THE DESERET 115
PRINCIPAL STOPS
The term "Principal" has been used synonymously for
"Prinzipal", "Diapason", and "Prestant" for that unique
quality of sound which is characterized as organ sound.
Since the principal has no orchestral counterpart, i t is
unique to the organ and is the natural sound produced by
open metal flue pipes in a pipe organ.
This sound provides
a foundation for the entire ensemble, and the importance of
the principal stops is evident when we examine the stoplist
of the Deseret 115.
The Great Division evolves around this Principal sound.
The 8' Principal, 4' Octave, 2' Fifteenth (super octave),
and a Mixture II comprise its "Principal Chorus".
The Swell
Division Principals are subordinate to the Great, thus are
less prominant and are found only at 8' and 4', and a
mixture voiced appropriately.
The Pedal principals provide a foundation for supporting
the manual tonal mass, as well as clarifying and defining
an independent line in contrapuntal music.
Principals at
16', 8',4', and a two-rank mixture complete and integrate
this division.
