Crash as piano chimed (5)
I believe the answer is:
prang
'crash' is the definition.
(to prang is to crash a car)
'piano chimed' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'chimed' becomes 'rang' (I've seen this before).
'p'+'rang'='PRANG'
'as' is the link.
(Other definitions for prang that I've seen before include "Crash (a motor vehicle)" , "nasty collision" , "knock" , "Crash involving a car" , "Possible argument with van" .)
