Sing part of barcarolle (5)

I believe the answer is:

carol

'sing' is the definition.
(I know that carol is a more specific form of the action sing)

'part of barcarolle' is the wordplay.
'part of' says the answer is hidden in the clue.
'CAROL' is hidden within 'barcarolle'.

(Other definitions for carol that I've seen before include "Female" , "Girl" , "See 1" , "Christmas ditty" , "Song celebrating the birth of Jesus" .)

I've seen this clue in The Guardian.
