Musical part that oboe has, but not violin (7)
I believe the answer is:
secondo
'musical part' is the definition.
(the lower part in a duet)
'oboe has but not violin' is the wordplay.
I cannot really see how this works, but
'not' could be 'con' (I've seen this in other clues) and 'con' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Other definitions for secondo that I've seen before include "Part of duet" , "participant in piano duet?" , "Musical" , "lower part" , "Work hands perform" .)
