Withdraw sequence of notes (6)
I believe the answer is:
retire
'withdraw' is the definition.
(both can mean to go back)
I cannot understand how the rest of the clue works.
(Other definitions for retire that I've seen before include "Pull back" , "Stop climbing the ladder" , "climb the stairs" , "Give up work for good" , "Withdraw - give up work - go to bed" .)
