The author argues that musical experience meets a human physiological and social need by supplying rhythmic stimulus that modulates bodily motion and emotional disturbance. Drawing on psychological, physiological, and sociological observations, she proposes toneurology as a field and contends that public agitation alters communal rhythms which music can help restore. Advocating free, state-supported musical instruction, she links such provision to the cultivation of native talent, expanded employment, and preservation of public mental health. Comparative national surveys, statistical appendices, a questionnaire, and practical recommendations are offered to support organized public investment in musical education.
