As the potentiality of mind provides the space for perception, thinking, emotions, concepts and language, another way to express this space as light and movement is through music and through colour.
In order to come to an understanding of preferences and dislikes for musical harmonies, one is offered an overview of the whole harmonic space, beyond the conventional understanding of what is comfortable.
Preferences for certain harmonies should not lead to fixations that prevent one from exploring the special characters and effects of less known harmonies and appreciating them.
In context the general tolerance towards the display of colour and its varying effects is broader; it is felt to be less disconcerting. This may be caused by its acceptance on a larger scale due to the development of the painting and of modern art.
To present the interaction of the effects of colour and tone, the intervals between the 12 tones within music are used to approach an approximate objectivity. These intervals and structures show the scales of music as colour and as degrees of light in progression.
This will be shown by first establishing the criteria for the three basic colours through the intervals and through explaining how they fuse within the modulation of the structure and function of each scale in the vertical and in the horizontal.
