In this thesis, the relationship between sound and colour has been analysed with two different methods. First, colours are applied to sounds using the psychological technique that is based on a study on synaesthesia. In the second approach, the ideal tones are linked to hues that are referring to adjectives. However, both methods have their disadvantages. This study investigates the relationship between timbres and colours with quantitative data from tonal structures.
In the first step, the relationship between timbres and colours is aggregated by conducting an experiment with subjects. The results are compared with the quantitative structure of the tone colours. From the result, four basic laws that define the causal relationship between timbre and cool or warm colours have been defined: overtone, fundamental frequency, length of sound and decay of sound.
