‘In music…pure tone, true pitch, exact intonation, perfect harmony, rigid rhythm, even touch and precise time play a relatively small role. They are mainly points of orientation for art… The unlimited resources for vocal and instrumental expression lie in artistic deviation from the pure, the true, the exact, the perfect, the rigid, the even and the precise. This deviation from the exact is, on the whole, the medium for the creation of the beautiful – for the conveying of emotion’[/i] – Carl E. Seashore.
