Drums, for example, could be supersonic (10)
I believe the answer is:
'drums for example' is the definition.
'percussion' can be an answer for 'drums'. I am not sure about the 'for example' bit.
'could be supersonic' is the wordplay.
'could be' indicates anagramming the letters.
'supersonic' anagrammed gives 'PERCUSSION'.
Can you help me to learn more?
(Other definitions for percussion that I've seen before include "Drums etc." , "Impact" , "kitchen" , "Section of orchestra" , "triangles etc" .)
