Charming composition heard (5)
I believe the answer is:
sweet
'charming' is the definition.
(thesaurus)
'composition heard' is the wordplay.
'composition' becomes 'suite' (suite is a kind of composition).
'heard' indicates a 'sounds like' (homophone) clue.
'suite' sounds like 'SWEET'.
(Other definitions for sweet that I've seen before include "Confection" , "attractive" , "(see 15 across) A Chinese sauce" , "Dulcet - dessert" , "S [SWEET] , basically" .)
