n. shrill sound produced by forcing air through a small opening (as between the lips or teeth); device which produces a whistle by forcing air or steam through an opening (i.e. tea kettle, train whistle); act of whistling

A simple whistle is a woodwind instrument which produces sound from a stream of forced air.Many types exist, from small police and sports whistles (also called pea whistles), to much larger train whistles, which are steam whistles specifically designed for use on locomotives and ships. Although whistles have a musical characteristic (for example train whistles sound a minor-seventh musical chord) whistles are not usually considered 'musical' in the sense of being able to play a chosen melody, but mainly the small whistles can also be used as a - very shrill and loud - noise and rhythm instrument. However, musical whistles exist, including any of several 2-octave musical instruments known as tin whistles (sometimes known as pennywhistles or low whistles), as well as the calliope (an array of separately actuable steam whistles), organ pipes and the recorder. Pea whistles are used in jazz and Latin music as a percussion instrument, and children often use them as a toy music instrument.
