I got some information from this website.
It is a document from the Philippines government.
he liangkit are long solo pieces accompanied by the gabbang and biyula. Unlike the sindil, they are not performed extemporaneously. The subject of the liangkit is wide—love, war, nature, and others. The Tausug lelling, adopted from the Sama, are part of the liangkit tradition, but are sung to the music provided by a guitar. They relate and comment on current events. One good example is the lelling narrating the entry of the Moro National Liberation Front forces into Jolo town in February
Lolai Liangkit is fast, just like the original Daling daling.
Tiyula Itum is slow, just like the origal dance of the Suluk people, pangalai.
