Dramatic performance observed in Europe rarely (5)
I believe the answer is:
opera
'dramatic performance' is the definition.
'opera' can be an answer for 'performance' (I have seen 'musical performance' mean 'opera' so perhaps 'performance' could also mean 'opera'). I am unsure of the 'dramatic' bit.
'observed in europe rarely' is the wordplay.
'observed in' indicates the answer is hidden within the clue.
'OPERA' can be found hidden inside 'europe rarely'.
Can you help me to learn more?
(Other definitions for opera that I've seen before include "Lohengrin, say" , "La Traviata or Tosca, say" , "Norma is one" , "Staged event" , "One with soap perhaps" .)
