Vanessa Van Anh Vo (left) and Diana Rowan, perform the tranh (36-string zither) and harp at The American Centre in downtown Ha Noi yesterday. Celtic harpist Diana Rowan shared skills during the hands-on presentation to explore the melodic embellishment of Middle Eastern music, the kinesthetic orientation of African kora playing and the upward hand stance of Latin American harp music. The practical lecture-demonstration-workshop focused on how to incorporate these techniques into harp arrangements and compositions. — Photo coutersy of American Embassy
