The monks leave the church after the mass in the Abbey of Keur Moussa, in Senegal, on May 19, 2021. - French Benedictines who founded Keur Moussa in 1963 were amazed at the sound of the kora, which they found could replace the organ when performing Gregorian chant. They produce between 40 to 50 koras a year in a small workshop and the instruments produced have become a point of reference for touring musicians and prominent members of griot families.
