PERCUSSION STOPS.
This class of stop is also now finding its way into organs more generally than heretofore. Resonating gongs giving, when skillfully used, effects closely resembling a harp have been introduced freely by the Aeolian Company in its house organs, and there seems no possible objection to such introduction. The tone is thoroughly musical and blends perfectly with the other registers. Under the name of "Chimes" these resonant gongs are now finding place in many Church and Concert organs. Tubular bells are also used in a similar capacity by all the leading organ-builders,
The greatest development in this direction is found in the Hope-Jones Unit Orchestra. In these instruments fully one-third of the speaking stops rely on percussion for production of their tones. Even small instruments of this type have all got the following percussion stops: Chimes, Chrysoglott, Glockenspiel, Electric Bells (with resonators), Xylophone, and carefully-tuned Sleigh Bells—in addition to single percussive instruments, such as Snare-drum, Bass-drum, Kettle-drum, Tambourine, Castanets, Triangle, Cymbals, and Chinese Gong.
As all these tone producers are enclosed in a thick Swell box, an artist is able to employ them with as much refinement of effect as is heard when they are heard in a Symphony Orchestra.
Mr. Hope-Jones informs the writer that he has just invented an electric action which strikes a blow accurately proportioned to the force employed in depressing the key, thus obtaining expression from the fingers as in the pianoforte. He will apply this to the percussion stops in organs he may build in the future.
When skilfully employed many of these percussion stops blend so perfectly with the flue and reed pipes that they become an important integral part of the instrument—not merely a collection of fancy stops for occasional use.
