We were talking about this in class the other day, so here’s the lowdown…
A Zaghareet (also known as an ululation) is a loud trilling that sounds something like “loo loo loo loo loo….” and often ends with an “eeeeeeeee” sound. It’s a combination of a high pitched, quite loud, “shriek” for want of a better word, as well as the “loo loo loo loo” trilling of the tongue layered on top.
The sound is made in celebration at weddings, births, and other auspicious events. Women usually cover their mouths while zaghareeting – some say this prevents evil spirits from entering; others say its to be polite and hide your open mouth.
It is an expression of joy, excitement, encouragement in the arab culture. It’s totally welcome to do when another dancer is on stage, also in a Zaffa (wedding parade in front of the bride and groom). It lends an air of excitement and charges the room/dance with a lively electric current.
It’s not appropriate for a dancer to do it while actually dancing though, it’s considered self congratulatory. Like patting yourself on the back!
