Music is much like Life: it begins and it ends it goes through stages it has an ebb and flow it is arbitrary yet structured it is abstract; relative only unto itself and once it stops, it's over.
The first thing that happens defines a point of relativity and around that rhythmic, melodic and harmonic axiom everything else is free to move; but, once it has ended, silence; perhaps applause.
Otherwise, peace.
An encore wasn't in the contract.
The only dissonance is internal; cognitive.
But, once it has happened, if if it significant enough, it creates waves that ne'er cease to ripple and refract and in such a way they are immortal and in such a way they are free to have a causal effect on the rest of Humanity; on the rest of Reality.
Music, much like Life, comes from Void into Existence, then it suffers the physical world and then it returns again to motionlessness, perhaps even Void again, and from there, who's to say?
So, I suppose, the moral is to not be afraid of who you are; learn it and come to terms with it and learn what drives it forth and then utilize that and do it to the utmost that others may see thy, as well as their own, Light that they, themselves, may be inspired to shine bright that Light of their own.
In that way and that way alone shall we bring forth an Enlightened World.
