The ālāpiṇī vīṇā was a medieval stick-zither veena in India, with a single string and a gourd resonator. Later forms added more strings. The instruments became prominent in Indian music after 500 C.E. as instruments of court music. Alongside the eka-tantri vina and kinnari vina it replaced the harp-style veenas and lute-style veenas. The instruments were used in Southeast Asia, both mainland and island nations, and were recorded in sculpture and relief sculpture. Similar instruments today include the Cambodian kse diev and Thai phin namtao.
