Finally note charity's songs of praise (6)
I believe the answer is:
psalms
'songs of praise' is the definition.
(I've seen this in another clue)
'finally note charity's' is the wordplay.
'finally note' becomes 'ps' (as in a postscript in a letter).
'charity's' becomes 'alms'' (alms is a kind of charity).
'ps'+'alms'='PSALMS'
(Other definitions for psalms that I've seen before include "Religious books" , "Sacred songs or poems" , "OT book" , "in the Bible?" , "Old Testament book of sacred songs" .)
