Music for funeral procession bishop possibly holds each month (4,5)
I believe the answer is:
dead march
'music' is the definition.
(dead march is a kind of music)
'funeral procession bishop possibly holds each month' is the wordplay.
I cannot quite see how this works, but
'procession' could be 'march' (march is a kind of procession) and 'march' is present in the answer.
'each' could be 'ea' (abbreviation) and 'ea' is found within the answer.
'bishop' could be 'dd' (DD stands for Doctor of Divinity) and 'dd' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for dead march that I've seen before include "Dispatch notes" , "Evidence of a sad occasion" , "Military movement" , "Music suitable for a funeral procession" , "Funeral pace by army escort" .)
