panpipes

Musical wind instrument consisting of a set of unpierced pipes in cane, clay, or other material, graded by length to provide a scale of pitches when blown across their opening. Invented according to legend in ancient Greece by the god Pan, the pipes flourish in the folk-music traditions of South America, Eastern Europe, and Japan. They produce a notably pure tone with a breathy onset.

The title instrument of Mozart's opera The Magic Flute (1791) is a set of pitch pipes, played by the character Papageno and symbolizing innocent pastoral humanity.
