Psychological experiments and analyses have been done to investigate quantitatively how the ideas of a musician are conveyed to the audience. The musician performed 1 minute of the beginning of the first movement of Mendelssohn's Violin Concerto with 10 different nuances: weak, powerful, bright, sad, sophisticated, beautiful, dreamy, fashionable, simple, and deep. Sixteen listeners, including the violinist, were asked to give their impressions of each of the 10 performances by the semantic differential method. The data obtained were analyzed by Kruskal's multidimensional scaling technique. The results revealed that, on the whole, the player's intention and the listener's impression, although there were individual discrepancies, were in general agreement.
