Scholar wild about English hymn tunes (8)
I believe the answer is:
chorales
'hymn tunes' is the definition.
'scholar wild about english' is the wordplay.
'wild' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'english' becomes 'e' (abbreviation).
'scholar' anagrammed gives 'chorals'.
'chorals' placed around 'e' is 'CHORALES'.
(Other definitions for chorales that I've seen before include "musical compositions" , "Simple hymn tunes" .)
