+tumblr While most sections are "power of two" in length (4 or 8 or 16 measures long), the verses are 6 measures (repeated twice), and the outro is extended for one extra phrase. There's also mixed meters, with each verse getting an extra beat, and the main riff dropping a beat in the last half the of the song.
