Lamma Bada yatathanna is a very old and well known Andalusian muwashah. The song is romantic poetry that recounts the beauties of the beloved one. “When she starts to move, amen, her beauty fascinates us. The movements are like a tree branch leaning”.
Here’s one translation of the words:
When the gossamer nymph appears,
My beloved’s beauty drives me to distraction;
Surrender
Surrender
When I am enraptured by a glimpse,
My beloved’s beauty is a tender branch caught by the breeze;
Surrender
Surrender
Oh my destiny, my perplexity,
No one can comfort me in my misery,
In my lamenting and suffering for love,
But for the one in the beautiful mirage;
My beloved’s beauty drives me to distraction,
Surrender
Surrender
