The arlabecca (Old Occitan: [aɾlaˈbɛka]) was a genre of Old Occitan lyric poetry.
First mentioned in an ensenhamen by Peire Lunel, the genre was supposed by François Raynouard to be a lament or dirge, and Emil Levy thought it a "kind of poetry".
It may derive from the Galician-Portuguese term for a rebec, arrabecca.
The term rebec (plural rebecz) can be found in Old Occitan references to both an instrument and a genre (as in the Leys d'amors, where it is undefined).
Possibly the rebec is the same genre as the arlabecca.
