A song for south Sudan: Writing a new national anthem
With hands on hearts, south Sudanese singers practise a song for their homeland.
If the south chooses independence in the on-going, week-long referendum, it will be the new national anthem for potentially the world's youngest country.
Students from Juba University in the southern capital were selected after a Sudanese-style X Factor talent show for musicians in front of cheering crowds.
"It started with the idea that at this moment in history, it was very important to start building a national anthem," said Joseph Abuk, chairman of the technical committee tasked with writing the anthem.
"We want to be ready for when we become a free nation."
Excitement is building in the south at the prospect of independence from former civil war enemies in the north.
In a baking hot concert hall in the steamy southern Sudanese capital, singer after singer took to the stage to perform their attempt at a new tune for their homeland.
The packed hall went wild at the end of each song, with people leaping to their feet and waving their hands in support.
Musicians were keen to make a change from the military-style march of Sudan's current national anthem.
The winner, from students and teachers at Juba University, wrote a softer, lighter tune - although critics say it struggles at times to squeeze the lyrics into the music.
But some misread the instructions and tried to fit the lyrics to current pop love songs.
A row of judges rated each tune - rapidly sending out those who came to sing "inappropriate" songs rather than more sombre national lyrics.
The crowd loved it all.
But this was not light-hearted entertainment: There were tears in people's eyes, and the lyrics remembered those who died in the struggle for the south to be able to choose its own future.
Some two million people died and four million were forced from their homes during the south's war with the north.
"The national anthem for me means I declare for everybody that I am free," said Mido Samuel, one of the composers of the winning tune, South Sudan Oyee! (Hooray!).
"We declare that we are independent now, we are a country."
The lyrics were written by a collective of 49 poets, who gathered together last year to write the verses, following guidelines set down by the government and army.
"The anthem had to have something about the south's history, its people, the land, its resources - and about the struggle that went on for 21 years," added Mr Abuk.
Then the organisers called on musicians to write a tune, holding three rounds of a music competition.
"Oh black warriors, let's stand up in silence and respect, saluting millions of martyrs whose blood cemented our national foundation," the anthem runs.
But it also offers a better, more optimistic vision for the future.
The south was left in ruins by decades of bitter civil war with the north, and people are hoping that by creating a separate southern nation, they will be allowed to live in peace.
"Sing songs of freedom with joy, for peace, liberty, and justice shall forever more reign," the lyrics run.
The song also calls the south the Land of Cush, a biblical reference to an ancient kingdom in the region.
"People were falling over or crying - this was quite an emotional moment," said Mr Abuk.
"You know if you have helped in the making of a thing that can bring tears, then I've done something that seems to be very meaningful to the people."
Having chosen the anthem, the new country's next step will be to decide on its name.
Lyrics of the new anthem, South Sudan Oyee!:
We praise and glorify you
For your grace upon Cush,
The land of great warriors
And origin of world's civilization.
Arise, shine, raise your flag with the guiding star
And sing songs of freedom with joy,
For peace, liberty and justice
Shall forever more reign.
So Lord bless South Sudan!
Oh black warriors!
Let's stand up in silence and respect,
Saluting millions of martyrs whose
Blood cemented our national foundation.
We vow to protect our nation.
Land of milk and honey and hard-working people,
Uphold us united in peace and harmony.
The Nile, valleys, forests and mountains
Shall be our sources of joy and pride.
So Lord bless South Sudan!
Both Sudan and the South are reliant on their oil revenues, which account for 98% of South Sudan's budget. But the two countries cannot agree how to divide the oil wealth of the former united state. Some 75% of the oil lies in the South but all the pipelines run north. It is feared that disputes over oil could lead the two neighbours to return to war.
Although they were united for many years, the two Sudans were always very different. The great divide is visible even from space, as this Nasa satellite image shows. The northern states are a blanket of desert, broken only by the fertile Nile corridor. South Sudan is covered by green swathes of grassland, swamps and tropical forest.
Sudan's arid north is mainly home to Arabic-speaking Muslims. But in South Sudan there is no dominant culture. The Dinkas and the Nuers are the largest of more than 200 ethnic groups, each with its own languages and traditional beliefs, alongside Christianity and Islam.
The health inequalities in Sudan are illustrated by infant mortality rates. In South Sudan, one in 10 children die before their first birthday. Whereas in the more developed northern states, such as Gezira and White Nile, half of those children would be expected to survive.
The gulf in water resources between north and south is stark. In Khartoum, River Nile, and Gezira states, two-thirds of people have access to piped drinking water and pit latrines. In the south, boreholes and unprotected wells are the main drinking sources. More than 80% of southerners have no toilet facilities whatsoever.
Throughout the two Sudans, access to primary school education is strongly linked to household earnings. In the poorest parts of the south, less than 1% of children finish primary school. Whereas in the wealthier north, up to 50% of children complete primary level education.
Conflict and poverty are the main causes of food insecurity in both countries. In Sudan, many of the residents of war-affected Darfur and the border states of Blue Nile and South Kordofan, depend on food aid. The UN said about 2.8m people in South Sudan would require food aid in 2013. The northern states tend to be wealthier, more urbanised and less reliant on agriculture.
