Direction in music (5)
I believe the answer is:
segue
'direction in music' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for segue that I've seen before include "Go on without interruption" , "Follow on without a pause" , "Smooth musical transition" , "In music, an immediate transition from one part to another" , "Move between songs, etc, without a pause" .)
