Vibration is a quality in the whistle corresponding to the resonance in the singing voice. It is produced by a slight quivering of the front of the tongue, particularly along the sides. Although not absolutely necessary, it is a quality which greatly enhances the whistle and produces a pleasing and sympathetic tone.

Moving the tongue rapidly back and forth in the mouth while continuously whistling, materially aids in acquiring this quality. The rapid practice of the wave, will also help to bring about desired results.

The motion of the tongue while vibrating has been likened to shivering. Any person who has been cold to the point of chills will understand the effect of shivering and its action on the tongue.

The vibrant quality should be more or less constant during the whistling of a selection, but never excessive, and never in evidence during the making of the bird figures. Keep it well under control.

To regulate too excessive vibration, tense the tongue more decidedly, and hold firmly both the under-lip and the chin.

There are some whistles so overloaded with vibration that they become shaky and uncertain, and (as a rule) fall below the desired pitch. Great care should be exercised, especially while executing bird-figures that the tone is clear and distinct, and not blurred, uncertain, or flat in pitch.
