spring giving way), bringing the stops drawn on another manual into
play. If playing on the Swell organ, the Choir stops will sound as
well when the keys are struck with extra firmness; if playing on the
Choir the Swell stops sound; and if playing on the Great the Double
Touch usually brings on the Tuba or Trumpet. It is thus possible to
play a hymn tune in four parts on the Swell and bring out the melody on
the Choir Clarinet; to play on the Choir and bring out the melody on
the Swell Vox Humana or Cornopean; or to play a fugue with the full
power of the Great organ (except the Trumpet) and bring out the subject
of the fugue every time it enters, whether in the soprano voice, the
alto, tenor, or bass.
In the latest Hope-Jones organs arrangements are made for drawing many
of the individual stops on the second touch, independently of the
couplers.
BALANCED SWELL PEDAL
At the commencement of the period of which we are treating (some fifty
years ago) the Swell shutters of almost all organs were made to fall
shut of their own weight, or by means of a spring. The organist might
leave his Swell-box shut or, by means of a catch on the pedal, hitch it
full open.
When, however, he wanted the shutters in any intermediate position, he
had to keep his foot on the pedal in order to prevent its closing.
The introduction of the balanced Swell pedal (Walcker, 1863) has
greatly increased the tonal resources of the organ. It is used almost
universally in this country, but strangely enough the country in which
the Swell-box was invented (England, 1712) lags behind, and even to-day
largely adheres to the old forms of spring pedal.
A further and great step in advance appears in recent organs built by
the Hope-Jones Organ Company. The position of the swell shutters is
brought under the control of the organist's fingers as well as his
feet. Each balanced swell pedal is provided with an indicator key
fixed on the under side of the ledge of the music desk, where it is
most conspicuous to the eye of the performer. As the swell pedal is
opened by the organist's foot, the indicator key travels in a downward
direction to the extent of perhaps one inch and a quarter. As the
organist closes his pedal, the indicator key again moves upward into
its normal position. By means of this visible indicator key the
organist is always aware of the position of the swell shutters.
Through electric mechanism the indicator key is so connec
