Rare Italian violin (5)
I believe the answer is:
amati
'rare italian violin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for amati that I've seen before include "One's played" , "fiddler" , "Noted Cremona violinmaking family" , "fiddling Italian family" , "Renowned violin-making family" .)
