The Aeolian harp is a musical instrument that is fashioned from a wooden sounding box with strings that stretch across the length of the box, fastened by two bridges on each side. The Aeolian harp is "played" as the wind blows against the strings, creating something called the von Karman vortex street effect. Because of this technique, it is commonly placed near a open window.

The Aeolian harp was popular during the Romantic Era, a period of artistic, literary and intellectual movements during the last half of the 18th century, characterised by an emphasis on intuition, imagination and feeling. The Aeolian harp is usually used as a symbol of afflatus or inspiration.
