Odd note, as in some Cuban music (6)
I believe the answer is:
rumbas
'some cuban music' is the definition.
(rumba is a Cuban dance style)
'odd note as' is the wordplay.
'odd' becomes 'rum' (rum can mean strange or dubious).
'note' becomes 'b' (musical note).
'rum'+'b'+'as'='RUMBAS'
'in' is the link.
(Other definitions for rumbas that I've seen before include "Cuban folk dances" , "Afro-Cuban dances" .)
