The name of the Waltz is taken from the Italian ‘volver’ - to turn.
The Waltz is in 3/4 time with the accent on the first beat and a basic pattern of step-step-close
At first religous leaders regarded the Waltz as sinful.
To the Continental courts it looked too much like sex.
This at first puzzled me but I once dated an Austrian Baroness who told me Europeans don't use their hips
