Device Measures Musical Talent (Apr, 1935)

Device Measures Musical Talent
A YARDSTICK for the measurement of musical talent, an automatic tone-variator, is now being used at Northwestern University to determine students’ ability to determine exact tonal pitch.
The machine contains 14 tuning-forks, set within one-quarter tone of each other. Two notes are struck in quick succession, and the students are asked which note was higher. Those that can detect the higher note consistently are keenly encouraged to study music. They are considered to be musically apt and talented.
Students with less sensitivity to tone are advised to study instruments with broader tone distinctions such as pianos and other keyboard instruments.
