His example of music as a balance between order and chaos is interesting. If you play entirely within the pentatonic major scale, for example, the sound will be something like a nursery rhyme. If you play a note outside of the scale (introduction of chaos), you have to resolve that dissonance or else it will sound like a bum note. This is true regardless of what scale or genre you choose to play. Other scales simply include more dissonance within them that still require resolution. People who say these things are subjective do not understand music theory. It is argued that people in the classical era had far less of an ear for dissonance, but this is unprovable. People today still find it offensive unless there is resolution.
