Great skill and brilliance (7)
I believe the answer is:
bravura
'great skill and brilliance' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bravura that I've seen before include "Audacity" , "Display of great daring" , "Display of boldness" , "Panache; daring" , "Great skill and brilliance in performance" .)
