Dance supremo Anna Pavlova denied six consecutive characters (5,4)
I believe the answer is:
bossa nova
'dance' is the definition.
(Brazilian dance)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bossa nova that I've seen before include "steps taken" , "(Music for) a Brazilian dance" , "Brazil's measure" , "lively dance" , "Brazilian music, rhythmically related to the samba" .)
