Question: when did the civil war start where songs sound similar to those in Arabia and from where most Beta Israel arrived?

Somalis have a rich musical heritage centered on traditional Somali folklore. Most Somali songs are pentatonic. At first listen, Somali music might be mistaken for the sounds of nearby regions such as Ethiopia, Sudan or Arabia, but it is ultimately recognizable by its own unique tunes and styles. That is, they only use five pitches per octave in contrast to a heptatonic (seven note) scale, such as the major scale. Somali songs are usually the product of collaboration between lyricists (midho), songwriters (lahan) and singers ('odka or "voice"). <SEP> Second Sudanese Civil War Part of the Sudanese civil wars Guerrilla forces of the Sudan People's Liberation Army celebrate over a disabled tank.

In addition, Israel is home to over 5,000 members of the African Hebrew Israelites of Jerusalem movement that are descendants of African Americans who emigrated to Israel in the 20th century, and who reside mainly in a distinct neighborhood in the Negev town of Dimona. The vast majority of these, some 120,000, are Beta Israel, most of whom are recent immigrants who came during the 1980s and 1990s from Ethiopia. Unknown numbers of black converts to Judaism reside in Israel, most of them converts from the United Kingdom, Canada, and the United States. <SEP> bir hima (arabic: بئر حما) is a rock art site in najran province, in southwest saudi arabia, about north of the city of najran. an ancient palaeolithic and neolithic site, the bir hima complex covers the time period of 2500–1000 bc. bir hima contains numerous troughs whose type is similar from north arabia to yemen. <SEP> after the start of the civil war, various new telecommunications companies began to spring up in the country and competed to provide missing infrastructure. somalia now offers some of the most technologically advanced and competitively priced telecommunications and internet services in the world. funded by somali entrepreneurs and backed by expertise from china, korea and europe, these nascent telecommunications firms offer affordable mobile phone and internet services that are not available in many other parts of the continent. customers can conduct money transfers (such as through the popular dahabshiil) and other banking activities via mobile phones, as well as easily gain wireless internet access.
