Near the lush fields of his village in Sudan's southern Blue Nile state, locals craft a traditional horn-like instrument.
Across the Blue Nile State communities, the instruments have been used for generations to usher in the harvest season, which typically begins in November after the wet season.
After more than 120 people were killed in clashes over access to land in Blue Nile state in July, the wazza was also played to celebrate a halt in violence.
Little is known about its history, but the wazza has strong links to rituals performed by the communities of the Blue Nile.
Wazzas, which are particularly common among the ethnic Funj people in Sudan's south, and vary in size, with some as long as two metres.
The size of each instrument determines its tone range, and wazza players perform in a band of up to 13 members.
The band leader "usually plays the smallest instrument."
