An ancient form of music, known as Kulintang, has been played for centuries throughout the Philippines. It first began as a signaling tradition, and is associated with other countries in Southeast Asia. There are different ways of playing Kulintang, depending on the region and group that is playing. Gong chimes are its main instrument, varying between the flat gong (gongsa) and the bossed gong. Flat gongs are circular metal discs suspended vertically by a hanging cord, and gives off a crashing sound. Bossed gongs have a raised centre boss and are suspended horizontally, and give off a tuned note sound. They are both played by striking the gong with two wooden beaters. Traditionally, a Kulintang set consists of 5 to 9 gongs arranged in order of lowest to highest pitch. Unlike many instruments, there is no fixed tuning for the gongs, giving each set unique pitch levels and timbre. This genre is still currently tied to my ethnicity; Kulintang continues to be played at feasts, festive gatherings, and parades. I would love to see a performance live!
