One takes a bow when playing this part in dramatisation (5)
I believe the answer is:
amati
'one takes a bow when playing this' is the definition.
(type of violin - a violin is played with a bow)
'part in dramatisation' is the wordplay.
'part in' indicates the answer is hidden within the clue.
'AMATI' is hidden within 'dramatisation'.
(Other definitions for amati that I've seen before include "Noted violin maker" , "family of craftsmen" , "Famous violin family" , "Old violin" , "Noted Cremona violinmaking family" .)
