The title of the piece, Reassons de Xarq (Xarq ecos) refers to the eastern region of Al-Andalus, Xarq-al-Andalus, also known as Xarquia

The piece is divided into three movements that are played without interruption: Algaida (sandbanks)- Mahual-Insiraf (exit).

Organization and choice of the different parameters are determined by associated fields (memories) of some known elements of Arabic music. For example: the maqam Nakriz, Malfouf rhythms, Aufar (accompanying to the hurn solo in Mahual)...
