Angel's harp's played around end of life (6)
I believe the answer is:
seraph
'angel's' is the definition.
(seraph is a kind of angel)
'harp's played around end of life' is the wordplay.
'played' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'end of' says to take the final letters.
The last letter of 'life' is 'e'.
'harps' anagrammed gives 'sraph'.
'sraph' going around 'e' is 'SERAPH'.
(Other definitions for seraph that I've seen before include "Angel of highest order" , "Angel - phrase (anag)" , "Phrase for a lofty angel" , "Angel with winged head of child" , "Leading angel" .)
