bravura
A highly technical or difficult piece, usually written for effect.
A display of daring.
Yet just as, in opposition to the majority, I admired Fosse's Nightsongs and The Girl On The Sofa, so I found myself absorbed by this 70-minute play; and, whatever it may mean, there is no denying the production's visual bravura.
Where it comes from
From Italian bravura (“skill”), from bravo (“good, skilful”). Compare bravado.
