Correspondence of Sound and Colour

Colours and Music Intervals

The colour represents components of white light spectrum. There are three primary colours blue, yellow and red, which cannot be obtained by mixing other paints. The other three colours (green, orange and violet) are the combinations of primary ones.

 

Clean music chord contains 6 harmonic intervals. For clarity sake, the intervals should be given the numerical value representing number of semitones in the interval.
For example, the C-major chord notes are Do, Mi, Sol and Do (in alt). The following intervals will be possible in this chord: Do/Mi (major third) 4 semitones, Mi/Sol (minor third) 3 semitones, Sol/Do of next octave (perfect fourth) 5 semitones, Do/Sol (perfect fifth) 7 semitones, Mi/Do (minor sixth) 8 semitones, Sol/Mi (major sixth) 9 semitones.
Thus, three intervals (3, 4, 5) are being the basic ones, and another three (7, 8, 9) are component ones since these can be obtained by composing 3, 4 and 5.

Thus, you can see the correspondence of two super-harmonious structures white light and the consonant chord, which consist of equal number of elements. The properties of light elements coincide with the properties of consonant chord elements, namely: three basic elements; composition of component ones out of them (optical for colours, and mathematical for octave semitones); contrast (for example, red contrasts with the green, perfect fourth is the conversion from the perfect fifth).
