 Kalangan or Tausug vocal music can be divided into narrative and lyric songs, and further into the lugu and the paggabang traditions.The luguh tradition denotes unaccompanied religious songs, while the paggabang tradition applies to "more mundane" songs that are accompanied by the gabbang and biyula (Trimillos 1972).Narrative songs tell a story and include all the sung kissa like the parang sabil.
