perfection happens

Not often. When it does in musical creation, is there a basic principle at work or in play that can be fetched by intuition, proposed by the listening, floating brain?

How about inevitability?

Chopin's "Nocturne in C-sharp minor, Op. 27, No. 1" flows and develops with an organic, unifying complexity of formal elements. Color and rhythm, line and structure, contrast and rhetoric. Also spiritual components -- disquiet and beauty, dream and melancholy, regret and candlelight. These aspects taken together build up a dynamical, living momentum, startling the ear and soul with a sense of ordained emergence, of aural fate.

The effect is like listening to music spontaneously write itself. The artistic logic unspools as if according to a graceful algorithmic compulsion. What we hear could not be otherwise. This night piece defies the natural and usual law of contingency. The fact that it exists is as necessary as time and gravity.

Is paradox also part of perfection? As this nocturne enters and interrogates the evening, a sense of improvisation blends into the destiny of the flowing equation.
