One of my students is learning to drum middle eastern rhythms. Has been taking lessons as and when he can afford to attend workshops etc. I also know of a drummer who has begun to teach my student more about rhythms and technique.

The big thing is the drummer who is teaching said he had never drummed for ATS dancers before. He is fully aware of the ATS improv situation, so was asking me what the cues to a drummer were ... I confess do not know any cues you would give to a drummer, because we have not had the opportunity/luxury of a live drummer before at our classes or performances - except for a bit mosh pit tribal jam at the end of concerts and soirees.

So his question is what are the cues for

Changing Rhythm
Faster
Slower
Loud
Quiet
Finish

If you were working all the time with the same drummer, you would build your own vocabulary of cues, or keep to agreed patterns and sequences. Any tips would be greatly appreciated.
