Composer bringing rapture (5)
I believe the answer is:
bliss
This clue is a double definition.
'composer' is the first definition.
(British composer Arthur Bliss)
'rapture' is the second definition.
(I've seen this in another clue)
'bringing' acts as a link.
(Other definitions for bliss that I've seen before include "of composing?" , "Extreme happiness" , "Intense happiness" , "Ecstasy; British composer" , "One who scored" .)
