Worries about the guitar parts (5)

I believe the answer is:

frets

I believe this clue is a double definition.

'worries' is the first definition.
(fretting is a kind of worrying)

'the guitar parts' is the second definition.
(I've seen this in another clue)

'about' is the link.

(Other definitions for frets that I've seen before include "bars" , "Worries; ornamental networks" .)

I've seen this clue in the Evening Standard.
