Composer wants broadcaster to include trains (with volume adjusted) (10)
I believe the answer is:
stravinsky
'composer' is the definition.
(Stravinsky is an example)
'broadcaster to include trains with volume adjusted' is the wordplay.
'broadcaster' becomes 'sky' (Sky is a television company).
'to include' is an insertion indicator.
'with' is a charade indicator (letters next to each other).
'volume' becomes 'v' (abbreviation for volume in book titles).
'adjusted' indicates anagramming the letters.
'trains' after 'v' is 'vtrains'.
'vtrains' anagrammed gives 'travins'.
'sky' enclosing 'travins' is 'STRAVINSKY'.
'wants' is the link.
(Other definitions for stravinsky that I've seen before include "Scorer" , "Igor __, "Firebird" composer" , "musician?" , "Igor -, Rite of Spring composer" , "he noted" .)
