Sarangi is one of another Nepali musical instrument which we can hear in most of the folk music/songs. It is different Sarangi than Indian one. Simply with 4 strings, Sarangi can be carved or plain but gives heart touching sounds. 
Gaine or Gandharbas are the ethnic group of Nepal who typically are surviving with Sarangi singing in either in public places, bus or professionally in studios and can be found many albums based on it.
