Bury a girl in the break (8)
I believe the answer is:
interval
'in the break' is the definition.
(I've seen this before)
'bury a girl' is the wordplay.
'bury' becomes 'inter' (to inter is to put into the ground).
'a girl' becomes 'Val' (short for Valerie).
'inter'+'val'='INTERVAL'
(Other definitions for interval that I've seen before include "what's between notes?" , "Break in activity" , "Pause, break" , "Break, gap" , "Pause; pitch difference" .)
