Wind section player (6)
I believe the answer is:
oboist
'wind section player' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oboist that I've seen before include "Player of woodwind instrument of treble pitch" , "Wind player" , "Musician who plays woodwind of treble pitch" , "Do I boost the musician?" , "Instrumentalist" .)
