Hi Dave,
No doubt, the Waltz is being danced with ever increasing flight and therefore the flight in all steps has increased over time.
What I am contesting, is very specifically the relative difference between the flight into step 1 versus the flight into step 2 ie., generally I disagree that the flight into step 1 is more than the flight into step 2, in the basic figures dancing the classical musicality.
To achieve the 'classical' Waltz character and musicality one should dance the end-of-3 into 1 into 2 with ever increasing flight. The entire mechanics of the basic steps are constructed from this musical intent that harmonises the flight with the way the musical tension is built and released in the music. And I don't see the very best messing with the 'flight' pattern I mention when dancing the basics (not that I'm prescibing that one should never...you will not find me using that kind of language).
Yes, there are other musical interpretations and choreographic possibilities and by all means dance them, no harm there. Variation is important.
