Bulbul_tarang
Bulbul tarang (Hindi: बुलबुल तरंग), Gurmukhi, (ਬੁਲਬੁਲਤ੍ਰੰਗ literally "waves of nightingales", alternately Indian or Punjabi banjo) is a string instrument from Punjab (ਪੰਜਾਬ) which evolved from the Japanese taishōgoto, which likely arrived in South Asia in the 1930s.[1]
The instrument employs two sets of strings, one set for drone, and one for melody. The strings run over a plate or fretboard, while above are keys resembling typewriter keys, which when depressed fret or shorten the strings to raise their pitch.[2]
