Alapini Vina
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.
Although the stick zithers and tube zithers are very similar, it is possible that they have different origins. Early paintings of stick zithers in India date back at least to the 5th century C.E. The earliest currently known stick zither is in the Caves of Ajanta at the end of the 5th century. After a period of assuming that tube zithers spread from India to Southeast Asia, modern scholars have been trying to decide if the tube zithers might have originated in Southeast Asia and spread to India. Whatever the origins, Indian influence on musical culture in Southeast Asia is recorded in the archaeological remains of past civilizations.
Similar instruments today include the Cambodian kse diev and Thai phin namtao.
