In view of the facts, the wisdom seems doubtful of requiring all teachers in the elementary schools to qualify in singing before being certified, as is now done in some places. There will be a goodly number of students, in the normal schools, who are fitted by original endowment to become excellent teachers, except that they will never be able to sing. In the case of a gift so specialized, it seems advisable to have a special teacher wherever possible, rather than to disqualify from teaching persons who cannot sing, but are otherwise well fitted to educate the young. Tests show that musical talent is specialized, but this is not to say that eminence in music can be attained by the stupid. The achievement of eminence in any endeavor calls for a grasp of life situations and a farsighted fidelity to sustained effort, which are functions of general intelligence. Also, for eminence in a musical career the intellectual functions which have to do with composition and interpretation are doubtless indispensable. A survey of the general intelligence of eminent musicians would probably reveal a median well above the average; and this would probably hold true even for singers. VI. ABSOLUTE PITCH By absolute pitch is usually meant the power to recognize a single musical note when heard, without comparison with any other tone, either objective or subjective. It seems to be an hereditary gift, and probably cannot be acquired by training. (Some doubt has, however, been recently cast upon the latter conclusion by the researches of Gough, who was apparently able to educate persons in this respect to a limited extent.) Statements regarding the frequency of those who possess this idiosyncrasy vary, from that of Boggs, who says that only a few persons have the gift, to that of Seashore, who declares that “the ability to name notes of a familiar keyed instrument on hearing a single tone is rather common among trained musicians, and may show itself very early in childhood.” Perhaps the discrepancies of statement arise through lack of complete agreement as to what should be meant by “absolute pitch.” If the definition is insistently limited to that often given, namely, “the power to name a single musical note when heard, without comparison with any other tone,” then no doubt the gift belongs to very few people, even those otherwise musically well endowed. Seashore holds that in these cases, it is probably not pitch as such which is recognized, but rather the timbre of the note. “The timbre of the low notes is entirely different from that of the higher notes, and the evidence seems to show that it is easier to remember a characteristic timbre than pure pitch in itself.” The gift of absolute pitch is a great advantage to a musician. It is included as a valuable asset in the talent-inventory of Révész. VII. TONE DEAFNESS
