The man in question intoned church music (4)
I believe the answer is:
hymn
'church music' is the definition.
(hymn is a kind of church music)
'the man in question intoned' is the wordplay.
I cannot really see how this works, but
'man' could be 'hy' and 'hy' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hymn that I've seen before include "Religious song of praise" , "Anthem" , "Special song" , "One sung in church" , "religious works" .)
