Let him, therefore, when “throwing his voice” to the roof, glance sharply upwards as soon as the words are uttered, and turn his head in a listening attitude; his example will be followed immediately by the audience, who naturally fall into the trap prepared for them, and, for the time being, are quite satisfied that the sounds do really come from the roof.
This is an advantage on which the ventriloquist can trade to an enormous extent, because the ear is so easily deceived. How difficult it is, when listening from within a closed room to a street organ playing outside, to tell whether the music comes from up or down the road. So with ventriloquism--the performer has but to modify the position of the vocal chords as indicated, and to fix his eyes upon the roof, when lo and behold! everybody is perfectly satisfied that the speech _does_ come from above.
Of the three “distant” voices, the “level” is, perhaps, the most useful and the most generally successful, because the mere fact of the entertainer being on the same plane as the door and the windows, from behind which people are supposed to converse with him, provides him with opportunities for using the facial muscles and for distorting sounds, and so heightening the illusion.
For instance, whereas he must turn full or three-quarter face when using the “roof” voice, he can carry on a dialogue on the “level,” sideways to the audience; or in the case where the stage possesses a door at the rear, he may often be permitted for a moment to turn his back.
Practice as before in the “bee drone” voice, without endeavoring to any great extent to shut off the sound in the throat. This may be done by curling up the tongue so that its tip presses against the back of the upper teeth.
If you are practicing by the side of the door, as you open it towards you the ventriloquially uttered sounds must be raised in tone and made more distinct by lifting the shutter from the throat, or, in other words, by allowing the tongue to resume its normal position, and the sounds to issue forth on the principle of the “bee drone.”
This voice is extremely useful for such illusions as “the man in the cellar attending to the gas meter,” &c. It calls particularly for a display of histrionic powers, and the mere fact of bending down, as the sounds appear to come from below, helps to give it the necessary subdued and “distant” effect. Whilst speaking very slowly in the “bee drone” thrust the chin forward, contracting the larynx as much as you possibly can; roll back the tongue to stifle the sound in the throat, and the illusion will be complete. Immediately you change from the “floor” to the natural voice, resume the standing position and speak with unusual distinctness. The contrast cannot fail to escape the notice of the audience, who will be quite convinced that you have indeed carried on a conversation with some one below.
