Does the prospect of performing the Standard Viennese Waltz reduce your partner to a trembling mass of hysteria?
Do the first strains of 6/8 time send her to hide in the restroom?
Can you hear her teeth grinding when you lead a closed change?
Do fleckerls make her scream?
I personally love this dance but have met several women - including one of my partners - who simply refuse to do it.
In many amateur competitions in the US, the SVW is only included at the Gold or Championship levels. Some have added it as an open competition for all other levels, distinct from the rest of the syllabus.
The fear-inducing aspects of the SVW are obvious: the deceptively challenging combination of speed and rotation. While it is - in my opinion - the most elegant of all dances, it is also clearly the most dangerous. I have seen even top-level couples fall heavily and always in the same step, the Reverse Turn.
I've always suspected that problems with the SVW stem from the character of the music. Getting "swept up" in the grandeur of some SVW pieces can make even an experienced dancer lose focus. At SVW's speed, just a split second of inattention can be disastrous. That same speed makes floorcraft very challenging if there are several couples on the floor, especially if they're dancing at different levels.
Unfortunately, due primariy to the erroneous perception that it is simple (only seven figures!), the SVW often receives little attention in many dancers' training.
It's also possible that the current put-ballroom-dancing-in-the-Olympics madness has prompted a decrease in emphasis on SVW because, when danced properly, it APPEARS to be very easy and not sufficiently athletic to impress the Olympic committees.
I look at it as the one ballroom dance with no easy steps.
