Kiribati folk music is generally based on chanting or other forms of vocalising, accompanied by body percussion. Public performances in modern Kiribati are generally performed by a seated chorus, accompanied by a guitar. However, during formal performances of the standing dance (''Te Kaimatoa'') or the hip dance (''Te Buki''), a wooden box is used as a percussion instrument. This box is constructed to give a hollow and reverberating tone when struck simultaneously by a chorus of men sitting around it. Traditional songs are often love-themed, but there are also competitive, religious, children's, patriotic, war and wedding songs. There are also stick dances which accompany legends and semi-historical stories. These stick dances or "tirere" (pronounced seerere) are performed only during major festivals.
