Spanish wine shop accommodating the French vocal style (9)
I believe the answer is:
cantilena
'vocal style' is the definition.
(I've seen this before)
'spanish wine shop accommodating the french' is the wordplay.
'spanish wine shop' becomes 'cantina' (Spanish term for a bar).
'accommodating' is an insertion indicator.
'the french' becomes 'le' ('the' in French).
'cantina' going around 'le' is 'CANTILENA'.
(Other definitions for cantilena that I've seen before include "musical exercise" , "song?" , "ballad" , "Melodic line" , "Musical part carrying melody" .)
