definition: The air itself is the vibrator in the primary sense. The standing waves are significantly confined within the instrument itself. The air-stream passes through the player's vibrating lips, so gaining intermittent access to the air column which is to be made to vibrate. The tubular body has a bore profile that is intermediate between conical and cylindrical. The body can be lengthened or shortened by connecting or disconnecting auxiliary lengths of tube.
