Traditional Afar music resembles the folk music of other parts of the Horn of Africa such as Ethiopia; it also contains elements of Arabic music. The history of Djibouti is recorded in the poetry and songs of its nomadic people, and goes back thousands of years to a time when the peoples of Djibouti traded hides and skins for the perfumes and spices of ancient Egypt, India and China. Afar oral literature is also quite musical. It comes in many varieties, including songs for weddings, war, praise and boasting.
