Crossword Genius

Loud expert features (4)

Ross

I believe the answer is:

face

'features' is the definition.
(thesaurus)

'loud expert' is the wordplay.
'loud' becomes 'f' (A musical term**).
'expert' becomes 'ace' (ace is a kind of expert).
'f'+'ace'='FACE'

(Other definitions for face that I've seen before include "set of features" , "Outward appearance" , "Confront - mug (slang)" , "'Cheeks, mouth, eyes etc (4)'" , "cheek" .)

I've seen this clue in The Times.
