As additional methods facilitating in some cases the transfer of stops must be named the "double touch" and the "pizzicato touch." The former, though practically introduced by Hope-Jones and found in most of his organs built during the last fifteen years, was, we believe, invented by a Frenchman and applied to reed organs. The pizzicato touch is a Hope-Jones invention which, though publicly introduced nearly twenty years since, did not meet with the recognition it deserved until recently. The earliest example of this touch in the United States is found in the organ at Hanson Place Baptist Church, Brooklyn, N. Y., 1909. In the French Mustel reed organ the first touch is operated by depressing the 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.
