Biraha

Biraha or Birha is a traditional folk song of Bhojpuri speaking people to highlight the feelings related to missing or meeting to beloved. Its place in folk songs is as important as that of Dwipadi in Sanskrit, Gatha in Prakrit and Barwai in Hindi. It is composed of two episodes. When one side says their point, the other side answers in the same verse. There is no limit to the number of quantities. The volume varies with the tune of the song. It indicates the intense longing of the spouse and the pain of love or feeling of separation from him. Separation is a king, a body that does not know separation, it is a living corpse. From Wikipedia
