Singer upset parson - took ring (7)
I believe the answer is:
soprano
'singer' is the definition.
(type of singing voice)
'upset parson took ring' is the wordplay.
'upset' indicates an anagram.
'took' is a charade indicator (letters next to each other).
'ring' becomes 'O' (O is the shape of a ring).
'parson' anagrammed gives 'sopran'.
'sopran'+'o'='SOPRANO'
(Other definitions for soprano that I've seen before include "Female singing voice" , "chorus girl, perhaps" , "Isolde, Violetta or 25" , "High female voice" , "Norman, perhaps" .)
