Charming volunteers repaired flutes (8)
I believe the answer is:
tasteful
'charming' is the definition.
(thesaurus)
'volunteers repaired flutes' is the wordplay.
'volunteers' becomes 'ta' (abbreviation for Territorial Army).
'repaired' indicates an anagram.
'flutes' is an anagram of 'steful'.
'ta'+'steful'='TASTEFUL'
(Other definitions for tasteful that I've seen before include "Aesthetically pleasing" , "Discriminating" , "with discrimination" , "Free of tawdriness" , "Let Faust have ability to enjoy good things" .)
