 Among groups like the Bagobo, the Kutiyapi ("Kudlung") is also used as a bowed instrument and is generally played to accompany improvised songs.A characteristic difference between Mindanaon Moro Kutiyapi and the non-Islamized Lumad equivalents is the style and set up of vocal accompaniment.Among the "Lumad" groups, the kudyapi player and vocalist are separate performers, and vocalists use a free-flowing method of singing on top of the rhythm of the instrument, whereas among the Maguindanao and Maranao, there are set rhythms are phrases connected with the melody of the kutiyapi, with the player doubling as the vocalist (bayoka), if need be.
