"Tatsulok" (Filipino word literally translated to Triangle; paraphrased as Pyramid) is a Filipino folk song originally composed by Rom Dongeto in 1989 and performed in 1991 by his trio folk-rock band, called "Buklod", which includes Noel Cabangon and Rene Boncocan. The song explains to a young man that there's an ongoing war and that the war is just the effect of a bigger problem. It tells the young man to take action and topple a pyramid upside-down to end a never-ending war between the rich and the poor.
