The kutiyapi, or kudyapi, is an indianized Filipino two-stringed, fretted boat-lute. It is the only stringed instrument among the Maguindanao people, and one of several among other groups such as the Maranao and Manobo. It is four to six feet long with nine frets made of hardened beeswax. The instrument is carved out of solid soft wood such as that from the jackfruit tree.
Common to all kudyapi instruments, a constant drone is played with one string while the other, an octave above the drone, plays the melody with a kebit or rattan pluck (commonly made from plastic nowadays). This feature, which is also common to other related Southeast Asian "boat lutes", which were influenced by varying degrees by Indian classical music concepts of melody and scale via Maritime Southeast Asia. (See Indosphere for more information on historic Indian cultural influence in Southeast Asia.)
For the Maguindanao, it is possible to arrange the beeswax frets into different patterns resulting in two different scales for the instrument. These are the binalig, a higher pitched scale similar to the pelog and accompanying style used to imitate that of the kulintang, and the dinaladay, a lower pentatonic scale used for teaching pieces of an abstract nature.ม้้่ม
In dinaladay, several tiers of difficulty revolve around main compositions: Patentek, Patundug, Banutun and Minudel; Patentek being the most straightforward, Minudel being the most-challenging.
Binalig scale pieces include several archaic compositions now not played on the kulintang, and of these pieces Malapankuno (cock crowing) and Mapalendad are included.
