Entertainment round piano with English artist (5)
I believe the answer is:
opera
'entertainment' is the definition.
(I've seen this before)
'round piano with english artist' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'piano' becomes 'p' (musical abbreviation).
'with' is a charade indicator (letters next to each other).
'english' becomes 'e' (abbreviation).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'o'+'p'+'e'+'ra'='OPERA'
(Other definitions for opera that I've seen before include "Musical extravaganza" , "musical performance" , "Tosca, for example" , "could be soap" , "art form" .)
