The purpose of this report is to document the results of the 1971-72 national assessment of the music education of elementary-secondary students and young adults. Music exercises were given to a national probability sample of 9-year olds, 13-year olds, 17-year olds (including high school dropouts and early graduates), and young adults between the ages of 26 and 35. The music exercises administered treat the five themes of musical performance, musical notation and terminology, instrumental and vocal media, music history and literature, and attitudes toward music. Variables used for the data analysis of eachof these themes include age, region of the country, sex, race, level of parental education, and size and type of community. This report shows the data analyses using graphs. No conclusions are drawn. Readers are expected to assimilate the data to draw their own conclusions.
