Bihu, an Assamese folk festival celebrates the jubilant three seasons that marks the beginning, middle and end of a year in the Assamese calendar. Rongali or Bohag, Kati or Kongali and Boghali or Magh Bihu, namely are celebrated at different times in the year and each one of them has a significant role in telling stories of the agrarian community. The folk songs assume great significance since they reflect the correct sentiment amongst the natives and further narrate the significance of the season. The Folk songs associated with Bohag Bihu are called Bihu Geets or Bihu Songs. Dhol, Gogona, Pepa, Sutuli and Bihu Taal are five major musical instruments used to compose tunes of Bihu Geet.
The Gogona is a type of jaw harp, a vibrating reed instrument that is used primarily in the traditional Bihu music in Assam. It is made of a piece of bamboo that has a bifurcation on one end. The solid end is gripped with the teeth and the free ends are then struck repeatedly with the fingers to emit the distinctive sound of Gogona.
