Sprezzatura is the art of making the difficult look easy.

That's bravura.

Sprezzatura is making the impossible, possible ... if only for a moment, a startling, shimmering, mind-shearing, joyous, epiphany of a moment.

A performance sublime
That's "Sprezzatura"
The best after that
"Ehh, bravura".

A single sprezz moment lasts a life-time.

It could even make a life-time otherwise wasted, well-lived.

A person can even die with sprezz. In fact, it's the only way to go.
