From expressive walking to expressive music performance
Opponent: Johan Bjurling
In this master thesis two experiments were conducted. In the first one it was investigated whether the acoustic parameters from expressive walking gaits could be used for controlling the sound of a musical instrument in order to communicate emotions. Subjects rated if they perceived the emotions as angry, fearful, sad, neutral or happy and whether a male or female performed the musical sequence. In the second experiment participants controlled timpani drum strikes by means of sliders connected to the average value and variation of some of the acoustic parameters used in experiment one. The participants were instructed to express the same five emotions as in experiment one.
Statistical analysis of the results show that the patterns of acoustic parameters such as tempo and sound level used in expressive walking could be successfully transferred to the control of musical stimuli. The trends for the parameters used for communicating different emotions were similar in both experiments as well as similar to the expressive cues known from literature in psychology of music.
