Beginning
Ending
Picking up impulses & taking them further
Taking part in something
Picking up rhythms from others
Playing with different rhythms
Trying out irregular dynamics
(Re-)do something with a time delay
Doing something again from before
Creating an echo
Starting ...at the same time as...
(De)synchronise with someone
Being faster than others
Being slower than others
Like leading & following in tango
Everything seems synchronised
The mood changes
It doesn't have to have a result.
Start Stop
Speed up
Slow down
Slow motion
Walking on an imaginary clock
Walking clockwise & counterclockwise
Crossing time
