Swanee whistle [swannee whistle, slide whistle, song whistle, piston flute, jazz flute, lotus flute, piston pipe, bird warble] (Fr. flûte à coulisse, sifflet à coulisse, jazzo-flûte; Ger. Lotosflöte, Stempelflöte; It. flauto a culisse)
- Hugh Davies
A stopped duct flute, which has no finger-holes, the pitch being altered by means of a piston or stopper, moved up and down inside the cylindrical tube from the lower end by one hand. Folk versions are normally made of cane or bamboo with a cloth-covered, padded piston-head; modern Western examples are usually of plastic or metal, with a tightly fitting leather washer for the piston-head (the principle resembles that of a bicycle pump)....
