Austrian city (6)
I believe the answer is:
vienna
'austrian city' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for vienna that I've seen before include "Strauss 'Tales from the . . . . . . Woods'" , "Austrian city of the waltz" , "Capital on the Danube Canal" , "European city for New Year's Day concert" , "On the Danube, it was home to many great composers" .)
