Embellished with some percussion (4)
I believe the answer is:
bell
'percussion' is the definition.
(thesaurus)
'embellished with some' is the wordplay.
'some' indicates a hidden word.
'BELL' is hidden within 'embellished with'.
(Other definitions for bell that I've seen before include "Ringing device" , "Tinkler" , "See 8" , "Instrument making ringing sound" , "eg Big Ben" .)
