At the Budapest University of Technology and Economics in 1956, we decided to start large-scale experiments on color harmony. The experiments and the processing of the experimental data were completed in 2006. The experiments described in this article were based on a long established experience that harmony content of different hue pairs greatly differ from each other. The vast majority of form...

In Western tonal music, the rules of harmony determine the order and music-structural importance of events in a musical piece: for instance, the tonic chord, built on the first note of the diatonic scale, is usually placed at the end of chord sequences. A brain response termed the early right anterior negativity (ERAN) is elicited when a harmonically incongruous chord is inserted within or at t...

Strategic uncertainty in game theory may have two di¤erent general sources, either alone or in combination: uncertainty because of the existence of a coordination problem, and uncertainty because of a con‡ict between one own and the other n players’ interests. Game harmony is conceived as a generic game property that describes how harmonious (non-con‡ictual) or disharmonious (con‡ictual) the in...

In 1956 we came to the decision at the Budapest Technical University to start large scale experiments on color harmony. The experiments and the processing of the experimental results have been completed in 2006, after 50 years of research work. Within the frame of the experiments 95 000 participants have carried out more than 36 million elementary observations and made elementary decisions. Onl...
