Fiddle perhaps somewhat melodramatically (5)
I believe the answer is:
amati
'fiddle' is the definition.
(violin created by the Amati family)
'somewhat melodramatically' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'AMATI' can be found hidden inside 'melodramatically'.
'perhaps' is the link.
(Other definitions for amati that I've seen before include "Great fiddle" , "A violinist" , "fiddling Italian family" , "Violin or cello made by a Cremona family" , "Renowned violin-making family" .)
