Model in quiet Spanish region (7)
I believe the answer is:
paragon
'model' is the definition.
(paragon is a kind of model)
'quiet spanish region' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'spanish region' becomes 'aragon' (region of Spain).
'p'+'aragon'='PARAGON'
'in' is the link.
(Other definitions for paragon that I've seen before include "An ideal" , "Model of excellence or perfection" , "A perfect person - pagan or what?" , "A model as of virtue" , "A Model of excellence, perfect person" .)
