(‘human whistling’ is the production of sound by means of expelling, and sometimes inhaling, a stream of air through the mouth)
.
(the air is moderated by the tongue, lips, teeth, or fingers to create turbulence, and the mouth acts as a resonant chamber to enhance the resulting sound, thus acting as a type of ‘helmholtz resonator’)
(‘whistling’ can also be produced by hands, or using an external instrument, such as a whistle or even a blade of grass or leaf)
(the ability to ‘whistle’ is quite unpredictable, and is possibly enabled by a ‘genetic trait’)
