Rhythmic processes can be understood as vibrational phenomena, as they are also described physically using the example of mechanical vibrations. In addition, one will have to look for the peculiarity of vibrations in the realm of the living, for which physical vibrations can only have a model character.
Thus, rhythm can be understood as a continuous movement between polar opposites, which is regularly repeated in similar time conditions. Going through the opposites results in emphasis. Their connection through the movement in the running process leads to unity and wholeness of the process. The principle of movement is inherent in all rhythmic phenomena, whether they are expressed in the spatial material or in the mental realm.
