Whistle

A whistle or call is a simple aerophone, an instrument which produces sound from a stream of forced air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ.

Famous quotes containing the word whistle:

    Instead of the scream of a fish hawk scaring the fishes, is heard the whistle of the steam-engine, arousing a country to its progress.
    Henry David Thoreau (1817–1862)

    O he did whistle and she did sing,
    And all the bells on earth did ring
    For joy our Saviour Christ was born
    On Christmas Day in the morning.
    —Unknown. As I Sat on a Sunny Bank. . .

    Oxford Book of Light Verse, The. W. H. Auden, ed. (1938)

    All we who prefer to live
    Have a little whistle we give,
    And flash, at the least alarm
    We dive down under the farm.
    Robert Frost (1874–1963)
