The effects of the human tone colours on mood

The aim of this study was to examine the effects of the different human tone colours on individuals' moods. The research design was determined as quasiexperimental design with test control group. In accordance with this purpose, the workgroup totally consisted of 240 prep students receiving education in preparatory class in 2017-18 academic year at a university in Zonguldak. One hand, the moods of the students related to the tone colours (soprano-alto-tenor-bas) that they listened was assessed with the 'Mood Scale' developed by Coskun & Gültepe (2014), on the other hand the physiological variations related to the tone colours that they listened was assessed with Physiological Scale (pulsimeter). The piano as a musical instrument play along with the tone colours utilized in the research. Hence, in order to determine whether the piano has any effect on moods or not, firstly a pilot study was conducted on 155 students who listened human voices both with the piano and without the piano. As a result of the pilot study, the students listened human voice along with a piano. In consequence of abnormal distribution, Mann-Whitney U test was used in the paired comparison of the tone colours, and Kruskal Wallis H test was used in overall comparison. Furthermore, in the physiological results of measurement conducted together with the main study comparison were performed with the Pearson product-moment correlation coefficient, then inter variance correlations were obtained with t test for paired samples and thereby t test results. While the data obtained from students were analysed with SPSS-25 statistical package, the wave graphics coupled with tone colours, amplitude analysis and spectrogram analysis were obtained with Matlab package. At the end of the research, it was acknowledged that there was a significant difference among the moods of the students related to human tone colours. On the other hand, it was determined that there was not a significant difference at the stage of physiological measurement associated with the study. In this study, there are also suggestions with regard to educational status and studies in the future.
