IV. RELATION AMONG VARIOUS ELEMENTS OF MUSICAL TALENT
Correlation has proved that sense of pitch and sense of time are largely independent of each other. Persons may stand high in one and low in the other. We know even now, therefore, that the elements of talent are independent or partially independent variables, and that excellence in one may be accompanied by inferiority in another. The successful musician is he who combines the necessary elements in high degree. Most children combine the elements in moderate or typical degrees of each, and are able to learn music and enjoy it in the ordinary manner. Only a few are capable of becoming professional performers. Schussler concluded that 5 to 10 per cent of the pupils examined by him might be justly classified as unmusical. A similar percentage would doubtless be classified as very musical, of whom a small proportion would be capable of outstanding musical achievement.
