Alapini veena and ekatantri veena

The ālāpiṇī vīṇā and the eka-tantrī vīṇā were medieval stick-zither and tube-zither veenas in India, with single strings and gourd resonators. The instruments became prominent in Indian music after 500 C.E. as instruments of court music. They 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.
