Ululation (pronunciation: i/ˌjuːljᵿˈleɪʃən, ˌʌl-/), from Latin , is a long, wavering, high-pitched vocal sound resembling a howl with a trilling quality. It is produced by emitting a high pitched loud voice accompanied with a rapid back and forth movement of the tongue and the uvula.
Ululation is practiced either alone or as part of certain styles of singing, on various occasions of communal ritual events (like for example weddings) used to express strong emotion.
Ululation is commonly practised in most of Africa, the Middle East and Central-to-South Asia. It occurs a few places in Europe, like Serbia, Cyprus, Malta and parts of Spain. It likewise takes place among the diaspora community originating from these areas. Ululation also occurs among Mizrahi Jews at all joyous occasions such as at a hachnasat sefer Torah (the dedication of a Torah scroll), circumcisions, communal celebrations, weddings,bar mitzvah celebrations, and most of all at henna celebrations. The cultural practice has spread to other Jews, particularly where members of different Jewish ethnic communities come together, and is also to be found among American Jews. The Hebrew word for ululation is "tsahalulim" (Hebrew: צהלולים). Recordings of various styles of ululations are commonly found in the music of artists performing Mizrahi styles of music. In Morocco it is known as barwalá or youyou.
