Whistling can also be produced by blowing air through enclosed, cupped hands or through an external instrument, such as a whistle or even a blade of grass or leaf.
The low whistle, or concert whistle, is a variation of the traditional tin whistle/pennywhistle, distinguished by its lower pitch and larger size. It is most closely associated with the performances of British and Irish artists such as Tommy Makem, Finbar Furey and his son Martin Furey, Old Blind Dogs, Michael McGoldrick, Riverdance, Lunasa, Donie Keyes, Chris Conway, and Davy Spillane, and is ...
