Dramatisation about a violin-maker (5)
I believe the answer is:
amati
'a violin-maker' is the definition.
(I've seen this before)
'dramatisation about' is the wordplay.
'about' indicates a hidden word (the clue goes around or about the answer).
'AMATI' can be found hidden inside 'dramatisation'.
(Other definitions for amati that I've seen before include "A violinist" , "Italian family of violin-makers" , "Violin or cello made by a Cremona family" , "Craftsman" , "fiddling Italian family" .)
