I'm teaching a dance class in Waltz, the music is of course in 3/4 time.
I wanted a way to describe to the students the beats in 2 consecutive bars, which I thought of as describing as '6/4' - I know that this is a mangling of time signatures. My co-teacher said to me she always thought of two bars of waltz as '6/8'.
Is either option 'correct', or is there a better way to describe the beats in this situation? As the description is for dancers to understand and not musicians to play, I don't need an answer which is 100.0% in accordance with the rules of music theory.
