Church said to produce psalm (6)
I believe the answer is:
choral
'psalm' is the definition.
'church said' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'said' becomes 'oral' (I've seen this before).
'ch'+'oral'='CHORAL'
'to produce' is the link.
(Other definitions for choral that I've seen before include "For a large number of voices" , "Scored for a choir" , "... his ninth ..." , "Sung by a choir" , "Beethoven symphony" .)
