Sound of our country composer (7)
I believe the answer is:
britten
'composer' is the definition.
(British composer Benjamin Britten)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for britten that I've seen before include "British composer associated with Aldeburgh" , "Benjamin -, twentieth century English composer (" , "English composer, d. 1976" , "Composer of Peter Grimes" , "See 8" .)
