combining voice and movement warm ups

I have been teaching people to warm up for years and I have not be separating my movement and voice warm up for as along as I can remember but in TEACHING movement and voice we tend to separate them. This is highly problematic and these days, in my own practice, I am going to a conscious extreme of joining the two from the beginning... not every rehearsal... but 90% of the time. It makes a huge difference and the transition into the 'work', be it creation or rehearsal is much smoother and I feel like it is increasing my skills in doing more complex movement and more complex vocal work. In the advanced class I am teaching right now, I am simply doing a fairly unstructured warm up in which i play music that people can sing over... I play it loud so that we do not have to worry about 'how we sound', we are not required to 'dance' to the music, nor are we restricted from it... simple... BE AWARE... this only is a good idea for people who can FEEL their whole body and are not riding the music, otherwise when the music stops it is a little like a surfer crashing on the beach and coming to a dead stand still... so FIRST you must learn to feel your body VERSUS feeling the music and being seduced into thinking it is YOU...
