TESTS NOW SHOW IF CHILD IS TONE DEAF OR MUSICAL
Has Junior a natural ear for music? Or are his piano lessons wasted effort? It’s easy to find out at once, according to Prof. Harold M. Williams, of the University of Iowa Child Welfare Research Station. Tests he has devised show whether a child has a real sense of rhythm and whether he can keep a tune in singing.
A rhythm hammer provides the first test. With it a.child is asked to tap on a plate, in time with the clicks of a special electric clock. Electric wires lead from plate and clock to another room, where on a chart whirled by a phonograph turntable an automatic pen records how closely the child has followed the clock’s beat. In another test, a child is asked to sing a song he has learned. An experimenter sits near by with a telephone transmitter. In another room, a special photographic apparatus makes a sound picture of the child’s singing and shows whether he can carry a tune.
