泛指所有中空圓筒或木製、金屬製、或其他材質的管樂器，以手指或手指觸鍵方式來按壓其身節上的孔洞。雖然多數長笛為管狀，有些為球狀（像是葫蘆笛）。長笛是由演奏者將嘴唇放在笛口吹氣，藉由吐氣長短來振動笛管內部。視長笛種類的不同，笛口可能位在尾端或側邊。絕大多數的現代長笛都採用貝姆式鍵制。

英文....	Generally refers to any musical wind instrument consisting of a hollow cylinder or pipe of wood, metal, or another material, with holes along its length that are stopped by the fingers or by keys that are opened by the fingers. Although most flutes are tubular, some are globular (as with a gourd flute). A flute is sounded by a stream of air from the player's lips striking against the sharp edge of an opening, breaking the air up and vibrating within the enclosed space. The air may be blown in from an end or from the side, depending upon the type of flute. Many, but not all, modern flutes are equipped with the Boehm system of keywork.
荷蘭語....	In algemene zin te gebruiken voor aërofonen, geluid voortbrengend door middel van een luchtstroom die vanaf de lippen van de bespeler over de scherpe rand van een opening wordt geblazen. In specifieke zin: de uit drie of meer delen bestaande, zijdelings aangeblazen fluiten, met of zonder (Boehm)kleppensysteem, in hout of metaal in westerse orkest-, kamer- en solomuziek.
西班牙語....	Úsese genéricamente para todos los aerófonos cerrados que suenan mediante una columna de aire producida al soplar el ejecutante con sus labios contra el borde afilado de un orificio, resultando lo que los expertos en acústica denominan un tono de borde. Use también específicamente para flautas traveseras de bandas occidentales, de conciertos, y de orquestas, hechas en madera o, a partir del siglo veinte, más a menudo de metal, de tres o más secciones, y usualmente aunque no exclusivamente equipadas con el sistema Boehm de digitación.
