Aeolian Harp

In the 19th Century, similar instruments to the one above became popula in many parks and homes of Germany, England and Scotland. It was called Äolsharfe ― Harp of Äolus. Similar instruments existed much earlier than the 19th century in East Asia. The ever changing melodies produced by the wind are extremely charming, and these instruments are made of weatherproof materials, so they are safe to put in the garden.
