The diwas is a type of bamboo panpipe made up of five to eight individual pipes with various pitches. Each pipe only has one hole and the instrument makes sound by bouncing air back on the blowing (open) end of the pipe. In some provinces in the Cordillera, the pipes are also played individually and are then called saggeypo. Tambuli and Budyong Used in: Southern Luzon (Tagalog regions); Mindoro and Eastern Mindanao
