Whistle

A sharp, clear sound made by forcing breath through a small hole between pursed lips, often used for signaling or attracting attention. It can also refer to a similar sound produced by an instrument or object, such as a tea kettle or a train. The action of whistling can be a deliberate act of communication, a spontaneous expression of emotion (like happiness or boredom), or a subconscious habit. The sound itself varies in pitch and duration depending on the control and technique of the whistler. Whistles can also be used in music as a melodic element or in certain forms of athletic competition, or to create a rhythmic beat.
