The number eleven is widely used as a metaphor for time and consciousness. The Rite of Spring, by Igor Stravinsky, has eleven repetitions of the same chord, while the Tool song “Jimmy” features eleven chords. The Negativland song “Time Zones” also features 11 repetitions of the same chord. There are many other examples of music featuring the number 11, such as the NFL’s players wearing the number 11. Football teams have 11 players on the field at one time.
