Heroically resisting pizzicato, perhaps? (7)
I believe the answer is:
unbowed
'heroically resisting' is the definition.
(unbowed means refusing to submit or give in)
I can't explain the remainder of the clue.
(Other definitions for unbowed that I've seen before include "Undo web? (anag)" , "pizzicato?" , "Not defeated" , "Not like Cupid" , "Not vanquished, free" .)
