Arrive on a higher note? (5,2)
I believe the answer is:
pitch up
'arrive' is the definition.
(to pitch up somewhere is to arrive there)
'on a higher note?' is the wordplay.
'on' says to put letters next to each other.
'a higher' becomes 'up'.
'note?' becomes 'pitch' (as in a musical note).
'up' put after 'pitch' is 'PITCH UP'.
(Other definitions for pitch up that I've seen before include "match cancelled in such circumstances?" , "Arrive" .)
