In ancient times, Jews living in Israel ululated if I am not mistaken. Is this practiced by Ashkenazi or Sephardic Jews today? Which other Jewish communities ululate? Ethiopians, Mizrahis, etc?
Are there any notable rulings or commentaries regarding ululation? Would it be considered immodest of a woman if she ululated in a public gathering such as a wedding or funeral? Is it prohibited for a man to do this?
