By now, scholars have written many papers relating to the influence of Confucianism in Southeast Asian countries generally and Vietnam: specifically, from the socio-political perspective. Yet, its influence in culture and arts still remains little concerned. The paper describes research findings on a popular cultural phenomenon in Vietnam (for the period from the 15th Century to the sycond half of the 19th Century), which is Ca Tru (song with clappers - or also known as singing geisha "hat a dao or hat co dau"), and influence of Confucian ethical standards on this type of cultural practice. Some well-known Confucian scholars liked to visit places of Ca Tru
and, some of them even had extramarital relationships with songstresses. Confucian ethics (representing the male chauvinism) made it favorable for formation and development of the geisha-courtesan cultural type.
