An artist of consummate skill (7)
I believe the answer is:
maestro
'an artist of consummate skill' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for maestro that I've seen before include "Rattle, say" , "Artist of consummate skill: conductor" , "musical genius" , "Virtuoso" , "Highly talented figure in a given field" .)
