Piece of counterpoint, roughly a couple of bars to start (5)
I believe the answer is:
intro
'start' is the definition.
(I've seen this before)
'piece of counterpoint roughly a couple' is the wordplay.
'piece of' indicates the answer is hidden within the clue.
'INTRO' is hidden within 'counterpoint roughly couple'.
'of bars to' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for intro that I've seen before include "Start of work" , "First bars of a musical composition" , "One starts" , "Prelude" , "Preamble" .)
