Country sound of composer Benjamin (7)
I believe the answer is:
britain
'country' is the definition.
(Britain is an example)
'sound of composer benjamin' is the wordplay.
'sound of' indicates a 'sounds like' (homophone) clue.
'composer benjamin' becomes 'britten' (Benjamin Britten).
'britten' sounds like 'BRITAIN'.
(Other definitions for britain that I've seen before include "See 10" , "Main part of UK" , "State" , "Island north of France" , "Where we live - Great!" .)
