This instrumental is based on the 3 different instruments standardly used in rock music: guitar, drums and bass guitar. The song starts off with a simple repetition from each instrument, but after a while, the guitar starts playing some chords. After around a minute of this, the guitar switches back to its original chords and then the drums are changed around. After another minute of this, the drums go back to the original beat and the bass playing changes. Then, another minute goes by and the bass playing goes back to normal. After a while, all the instruments start playing their special segments from before. The name for this song "Triad," is about the combination of these instruments to form Tool's very technical playing style.
