Not only musicians and psychologists, but also committed music enthusiasts and experts often voice the opinion that the beauty of music lies in an expressive deviation from the exactly defined score. Concert performances become interesting and gain in attraction from the fact that they go far beyond the information printed in the score. In his early studies on musical performance, Carl Seashore discovered that musicians only rarely play two equal notes in exactly the same way. Within the same metric structure, there is a wide potential of variations in tempo, volume, tonal quality and intonation. Such variation is based on the composition but diverges from it individually. We generally call this ‘expressivity’. This explains why we do not lose interest when we hear different artists perform the same piece of music. It also explains why it is worthwhile for following generations to repeat the same repertoire. New, inspiring interpretations help us to expand our understanding, which serves to enrich and animate the music scene.
