Revolutionary abruptly dubbed and cut Bohemian music (5)
I believe the answer is:
polka
'music' is the definition.
(polka 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 polka that I've seen before include "Bohemian movement" , "An originally Bohemian dance" , "Folk dance" , "Take rapid steps" , "Lively dance of Bohemian origin" .)
