Countries and musicians throughout the region take part in this 23rd conference and festival of Arabic music.
Over 70 musicians participate this year from 12 countries, including competitors in the Arabic version of the popular television contest The Voice.
The festival includes a display of musical instruments and two art exhibitions and a special section in honour of people who have contributed to Arabic music such as singers Hany Shenouda and Sabah Fakhri and instrument maker Nasr Mahamed Tawfik.
Egyptian Hany Shenouda is known for combining western lyrics with Arabic rhythmics and traditions and Syrian-born Sabah Fakhri for his revitalisation and popularisation of traditional musical forms and his interaction with his audiences.
Most of the events take place at Cairo Opera House.
