Cremona violin-maker (5)
I believe the answer is:
amati
'cremona violin-maker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for amati that I've seen before include "Renowned violin-making family" , "fiddling Italian family" , "Famous violin-maker" , "Craftsman" , "Famous violin family" .)
