Much of the Arab pop music is mainly produced in Cairo and Beirut is a secondary center. It is an outgrowth of the Arabic film industry which is also present in Cairo. The ughniyah or in English "Arab song" primary style is a one that synthetically combines pop melodies with elements of different Arab regional styles. Most of the songs are in a minor key, and themes focus on varying moods of longing, melancholy, strife, and generally love issues. Arab pop has found fans in communities of expats especially in France and the United States.
The early days of Arabic pop where more a traditional and classical style of music. Artists such as Umm Kulthum and made it acceptable for females to perform. In the 1970s with the rise of Western artists and the death of the early artists such as Umm Kulthum Western sounding Arabic pop began to take its initial shape. Artists like Dalida began to blend disco with the traditional Arabic songs and met with success. By the early 1990s artists such as Nawal Al Zoghbi rose to fame with their Western sounding Arab Pop.By the mid to late 1990s a style of Arab Pop Princesses rose to prominence akin to the west, defining the genre as it's now known today in the modern world.
