he keys about a sixteenth part of an inch. This produces a
soft sound. A louder and different tone is elicited upon pushing the
key further down. In the pipe organ the double touch is differently
arranged. The first touch is the ordinary touch. Upon exerting a much
heavier pressure upon the key it will suddenly fall into the second
touch (about one-eighth of an inch deep) and will then cause an
augmentation of the tone by making other pipes speak. The device is
generally employed in connection with the couplers and can be brought
into or out of action at the will of the organist. For instance, if
the performer be playing upon his Choir Organ Flute and draws the Oboe
stop on the Swell organ, he can (provided the double-touch action be
drawn), by pressing any key or keys more firmly, cause those particular
notes to speak on the Oboe, while the keys that he is pressing in the
ordinary way will sound only the Flute.

The pizzicato touch is also used mostly in connection with the
couplers. When playing upon a soft combination on the Great, the
organist may draw the Swell to Great "pizzicato" coupler. Whenever now
he depresses a Great key the Swell key will (in effect) descend with
it, but will be instantly liberated again, even though the organist
continue to hold his Great key. By means of this pizzicato touch (now
being fitted to all Hope-Jones organs built in this country) a great
variety of charming musical effects can be produced.

THE UNIT ORGAN.

The Unit organ in its entirety consists of a single instrument divided
into five tonal families, each family being placed in its own
independent Swell box. The families are as follows: "Foundation"--this
contains the Diapasons, Diaphones, Tibias, etc.; "woodwind"--this
contains Flutes, Oboes, Clarinets, etc.; "strings"--this contains the
Gambas, Viols d' Orchestre, Dulcianas, etc.; "brass"--this contains the
Trumpets, Cornopeans and Tubas; "percussion"--this contains the
Tympani, Gongs, Chimes, Glockenspiel, etc.

On each of the keyboards any of the stops, from the "foundation" group,
the "woodwind" group, the "string" group, the "brass" group and the
"percussion" group, may be drawn, and they may be drawn at 16 feet, at
8 feet, and, in some instances, at 4 feet, at 2 feet, at twelfth and at
tierce pitches.

Arranged in this way an organ becomes an entirely different instrument.
It is very flexible, for not only can the tones be altered by drawing
the vario
