The trend toward the separate measurements of many human abilities has grown out of realization that skills vary in any individual and that it is as important to understand intra-individual differences-strengths and weaknesses-as to have indications of comparative standing among other individuals.
One important area of ability not tapped by typical scholastic of general aptitude tests is that of musical ability. Some of the uses of a musical aptitude test are: educational and vocational counseling, admission to music instruction in school, and selection for membership in bands and other musical organizations. Not all of the facets of musical aptitude are known, but there are several fundamental capacities that can be assessed.
This test provide the separate measures for eight of these capacities: rhythm, timbre, tonal movement, time, loudness, pitch, tonal memory and pitch-rhythm imagery.
This test was designed for use with subjects from fourth grade level up. Although norms are presented only for various educational levels, the tests have been successfully used with adults. Norms (percentile equivalent) for this test were presented for three educational levels, grades 4-6, 7-9, and 10-12. These levels were selected after the study of score distributions for single grades; differences among adjacent grades were generally too small to warrant presentation of norms for every grade.
Sex differences in scores on the eight measures were also investigated at the various grade levels. The differences were found to be very small and inconsistent from one level to another. Combined sex norms were therefore formulated.
The reliability of the test was estimated by means of split-half coefficients, which is shown in Table 5 for each measures at the grade levels represented in the norms groups. The means, standard deviations, and number of cases relevant of these coefficients are those shown in the norms table (Table 6).
