"Is this a waltz?"

The Viennese ball season has begun.

Vienna has no shortage of spectacular venues (this is in the town hall):

Unlike at Oxford balls, the main point of the thing is dancing - as pictured here, the ball is opened by waltzing débutantes dressed in white, after which couples of all ages take to the floor and the orchestra continues all night. Viennese waltzes feature heavily, of course.

BOKU, the university where I work, has its own ball in January in the Hofburg ballroom. This is not generally open to the public, but I saw it recently during an art and antiques show which C gave me a free ticket to:

I look forward to dancing there!
