A Philippine set of 4 large, hanging gongs used in the Maguindanao kulintang ensemble. It functions as a secondary melodic instrument after the main melodic instrument, the kulintang. When played solo, the gandingan allows fellow Maguindanao to communicate with each other, allowing them to send messages or warnings via long distances. This ability to imitate tones of the Maguindanao language using this instrument has given the gandingan the nickname 'talking gongs'.

The instrument comprises 4 large, shallow-bossed, thin-rimmed gongs, vertically hung, either from a strong support such as a tree limb or housed in a strong wooden framed stand. The gongs are arranged in graduated fashion in pairs with knobs of the lower-pitched gongs facing each other and the higher-pitched gongs doing the same. This arrangement is similar to the arrangement of gongs on the horizontally laid kulintang – so much so, in fact that master musicians say it duplicates the pattern of intervals used on the 4 lower-pitched gongs of the kulintang.
