Stopped flute pipe, usually of limited musical range, used in orchestrions (e.g., Hupfeld Pan Orchestra, Sinfonie Jazz, and late Helios styles) and organs, mainly circa 1910-1930, but especially in the 1920s. Usually equipped with a vibrato device which, together with music arranged to "slide" (i.e., glissando effect) from one note to the next, imparts a haunting rising and falling tone to the music. Usually played as a solo effect using specially-arranged music rolls. * Compare to the Swanee whistle. * German: Lotos Flöte.
