The name Flageolet denotes an open flue stop of 2' or 1' pitch, rarely 1 1/3', usually a flute. It is usually made of cylindrical metal pipes, but has also been made of wood, particularly in Victorian England. Various sources have equated it with the Piccolo, Flautino, Sifflet, and Schwiegel; others sources maintain that it is (or should be) softer than the Piccolo. While Flageolet should properly be used for a stop imitative of the instrument of the same name, in practice it has been used for any high-pitched flute stop. Douglass dates it from the 16th century. The name Petit is mentioned only by Wedgwood, who says: �Petit - (Fr.) Petit = small. 1 ft.; sometimes 2 ft. A Flageolet, at Ansprech.�
