I was trying to create δ here by creating dissonance to harmony and resonance and using wave cancelling where there is a final change that can only be felt in your body through the impending intersection of waves. This is where, by using calculus and δ, you can create new and unique sound art. To a smaller degree, this was done in the years ago and was called stereo, which created the illusion of sound moving in your head.Here I am taking it one step further. At some points the wave cancelling will create one effect, and then immediately change, like songs might on a mix tape. In that example, it's not the songs that are important, but the change between the two. It creates a new emotion that either song could not.In this example, the actual effect is not played, but it is felt in your mind as you listen to the change.Doing this will not work with the effect alone as you approach the point of δ, but when you hear it together, a separate sound evolves, creating a new sound that can only be created by involving the first two sounds. Also, you may need headphones, or at least you will need stereo, to hear this.
