Tones in Space

A tone exists and travels through space and the ear can listen. If the ear perceives this tone the voice can reproduce it. Tomatis and Kodaly realized this, the complete connection between the ear and the voice. Space also exists between two tones even if sounded at the same time. In music we call this an interval. 

Rhythm is a more physiological aspect to music. Similar to the mind, we can not see or touch tones in space but with practice we can use our ears to perceive them.
