Italian violin maker (5)
I believe the answer is:
amati
'italian 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 "Noted violin maker" , "Italian family of violin-makers" , "Violin or cello made by a Cremona family" , "Noted Cremona violinmaking family" , "Famous violin family" .)
