organ [3]

Wind instrument with several keyboards; it produces sound by means of pipes that are fed by a blower.
organ [3] Pipe that vibrates when pressurized air passes through a narrow horizontal aperture called the mouth. Opening through which air from the blower enters the pipe. Narrow slit through which air from the foot passes after hitting the languid. Lower part of the conical pipe through which air enters; it is attached to the upperboard. Flat portion of the foot; it forces air onto the languid. Horizontal aperture on the front of the pipe between the body and the foot; air escapes through it to produce sound. Flat part of the pipe that breaks up the air exiting the flue, causing the air column in the body to vibrate. Upper part of the pipe; it controls the volume of vibrating air and acts as a resonator. Metal plate that the air strikes before exiting the flue.
