The Long-Term Predictive Validity of the Musical Aptitude Profile Relative to Criteria of Grades in Music Theory and Applied Music

Abstract

In a longitudinal follow-up investigation spanning approximately five years with an initial sample of 135 freshman music majors, the Musical Aptitude Profile (MAP) (Gordon, 1965) revealed some statistically significant validity coefficients for Tonal Imagery subtest scores, Rhythm Imagery subtest scores, and the Composite Score of the MAP relative to course grades in music theory for the first three semesters of coursework and grades in the components of these music theory courses. Whereas the Tonal Imagery subtest was found to be the most valid predictor of success in the three components of each of the first two courses in music theory, it afforded no significant predictive validity for grades in any of the components of the third semester course. The Rhythm Imagery subtest of the MAP, however, continued to be modestly valid in predicting grades in the sight-singing and ear-training components of the third semester of music theory. No statistically significant validity coefficients were obtained for the MAP as a predictor of grades in the fourth and fifth semesters of music theory coursework or in applied music.
