Aeolian

Aeolian is an adjective and noun used in several disciplines to denote wind-related things, places connected to wind, and musical concepts. The term comes from Aiolos, the Greek god of the winds; the spelling "Aeolian" is common, though "eolian" is also used in some technical contexts, especially in geology.

In geology and geomorphology, aeolian processes describe erosion, transport, and deposition by wind. They shape landscapes through deflation, abrasion, and dune formation, and contribute to features such as dunes, loess deposits, and desert pavements.

The Aeolian Islands are a volcanic archipelago off the north coast of Sicily in the Tyrrhenian Sea. The main islands include Lipari, Vulcano, Stromboli, Salina, Panarea, Filicudi, and Alicudi. The islands are known for volcanic activity, rugged coastlines, and their scenic landscapes.

In music, the Aeolian mode refers to the natural minor scale; in modern usage it is equivalent to the natural minor scale on a given tonic. Historically part of the medieval system of modes, the Aeolian mode underpins many minor-key melodies and is often described as the minor sound in Western music.

Other uses include the Aeolian harp, a wind-activated string instrument celebrated in poetry and literature.
