Tomatis talked of the 'ear of the body'. Our perception of ourselves in space, our movements being carried out in a balanced, co-ordinated manner. Think of the timing involved in kicking a ball for example.
When teaching a rhythmic phrase to someone whose ear does not function as well as it might, it is clear how fundamental our sense of space(balance) and time(co-ordination) is to the execution of that phrase.
I am in the process of seeing to what extent sound rhythmic tuition helps improve ones balance and co-ordination, and for some result in a different perception of the whole.
