Zaghareet (pronounced “zah guh REET”.) also known as a ululation is a long, high-pitched, wavering yet sharp trilling howl created with the fast movement of the tongue to show heightened emotion. On the most part its a celebrational sound used to give praise and express joy within several contexts: ritual, singing, celebrations/events but it can be also be used as a sound of deep mourning depending on the culture using it.
