The Schlicker Organ
The
nine rank Schlicker organ at Grace was built by the Schlicker Organ
Company of Buffalo, New York. Dr. Paul Bunjes served as consultant on
the project. The two orders of organ pipes are determined by the method
of exciting the air column:
(1) the edge tone or labial pipes, and
(2)
the reed tongue or lingual pipes.
The organ at Grace has one rank
of the latter type with the remainder of the ranks being of the labial
type. The two families of organ pipes are determined by the basic shapes
of the pipes: cylindrical and conical.
Within the labial family of
pipes there are five different :
(1) open cylindrical pipes,
(2) open conical pipes,
(3) covered cylindrical pipes,
(4) covered conical pipes, and
(5) partly covered pipes.
Within the lingual family there are four shapes:
(1) pipes having a cylindrical resonator,
(2) pipes having a conical resonator,
(3) pipes having a multiple resonator, and
(4) pipes having a fractional resonator.
A third factor to be considered in organ tone is that of the cross-sectional area of the pipe. There are
five genera:
(1) very narrow-scaled pipes,
(2) narrow-scaled pipes,
(3) moderate-scaled pipes,
(4) wide-scaled pipes, and
(5) very wide-scaled pipes.
A
final consideration for organ construction is unification. A straight
organ uses each rank of pipes only once. A unified organ is one in
which a rank is "borrowed" or made to play at a different pitch
and/or on another manual or pedal by means of an electrical switch
called a "stop tablet." The organ at Grace is unified, with s a "tonal
fund" of nine ranks, each of which is used approximately three times
at different pitches: once on Manual I, once on Manual II, and once on
the Pedal. A total of 27 stop tablets results. Maximum use of each rank
is thus achieved without overusing the rank. The organ is of "classic"
design, lacking the swell box which appears on organs designed from the
romantic era onward.

The Steingraeber Piano
In 2001, Grace acquired a Steingraeber concert grand piano as a gift from Grace charter member Sylvia Manchester. Manufactured by Steingraeber und Söhne of Bayreuth, Germany, the concert grand at Grace is in great demand as one of the best keyboard instruments in Boulder, enhanced by the excellent acoustics of the Grace sanctuary. It is a wonderful resource for both worship and performance.
