Music arranged for oboe, cleverly using both hands (6)
I believe the answer is:
bolero
'music' is the definition.
(bolero is a kind of music)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bolero that I've seen before include "Maurice Ravel's most famous work" , "Genre of slow-tempo Latin music associated with Spain and Cuba" , "Upper garment or music piece by Ravel" , "Spanish dance - item of clothing" , "Lively Spanish dance" .)
