One is the gabang, the Muslim xylophone. It is trapezoidal in shape, with the keyboard made up of flattened pieces of bamboo of different lengths and sizes. The longest lies across the wider end, the keys tapering down in size to the smallest piece on the narrowest end of the instrument.
The talunggating is the Philippine marimba, similar to the gabang in construction. Both are played in the same way, except that the bulky talunggating has several resonators, while the smaller gabang has none. In parades the gabang is preferred because it is portable.
The hardest instrument to construct, but the easiest to play, is the tipangklung. Perhaps you would call it the bamboo piano or harp. Actually, it is a combination of both. The keyboard consists of 36 bamboo keys attached to an equal number of bamboo tubes.
The bungkaka is the clapper. In playing it, the split end of the bamboo tube is struck against the palm of the left hand, with the prongs producing the accent and rhythm. The talunggating and the tipangklung provide the melody.
The Pangkat Kawayan also uses the drum, the gong, the triangle and cymbals. But the bamboo instruments dominate the music.
Among the Maguindanao, this includes: the kulintang (strung stand, serving as the main melody instrument of the ensemble), the agung (the largest gongs of the ensemble providing much of the lower beats, either coming in a pair of two or just one alone), the gandingan (four large vertical gongs aligned front to back, used as a secondary melodic instrument), the dabakan (an hour-glass shaped drum covered in goat/lizard skin) and the babendil (a singular gong used as the timekeeper of the entire ensemble).
Among the indigenous peoples of the Central Cordilleras of the northern island of Luzon, music is also played with gongs, but unlike those of southern repertoires, these gongs, called Gangsa, are unbossed and have their origins in mainland Asia. Music is usually played to accompany dance, and because of this is mostly percussion based.
Other indigenous instruments include a bamboo zither, log drums, the Kudyapi two stringed boat lute and various flutes, including some nose flutes used by northern tribes.
