Alemu Aga (Amharic: ዓለሙ አጋ?) (born 1950) is an Ethiopian musician, singer, and master of the bèguèna. Born in Entotto, near Addis Ababa, Alemu became interested in the begena (a ten-stringed member of the lyre family, also known as "King David's Harp") at the age of twelve, when a master of the instrument stayed next door to his family, the Aleqa Tessema Welde-Emmanuel. Aleqa Tessema began teaching at Ras Desta school, where Alemu was a pupil. As well as studying the begena at school, Alemu carried his master's instrument to and from school, and thus benefited from more of Tessema's time.
