The Gandingan is a Philippine set of four large, hanging gongs used by the Maguindanao as part of their kulintang ensemble When integrated into the 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 wantings via long distances. The ability to imitate tones of the Maguindao language using this instrument has given the gandingan connotation: the talking gongs.
