Leta S. Hollingworth, Special talents and defects (1923)
“ III. THE ANALYSIS OF MUSICAL TALENT Since about the year 1915, psychologists have turned somewhat from the study of the nature of music to the investigation of the musical person. They have raised the questions: In what way does the musician differ from others in his psychophysical equipment? Why are some persons unable to produce or appreciate music?The pursuit of these questions led immediately to an analysis of musical talent, for it was evident at once that a great variety of subsidiary functions contribute to any kind of musical performance. ”
