Pole, peaceful and musical (5,7)
I believe the answer is:
south pacific
'musical' is the definition.
(I've seen this before)
'pole peaceful' is the wordplay.
'pole' becomes 'South Pole' (South Pole is an example).
'peaceful' becomes 'pacific' (similar in meaning).
'south'+'pacific'='SOUTH PACIFIC'
'and' acts as a link.
(Other definitions for south pacific that I've seen before include "Musical - ocean area" , "1949 musical by Rodgers and Hammerstein, made into a film in 1958" , "Part of ocean - musical" , "Musical (where Easter Island can be found?)" .)
