| Abstract | |
Absolute pitch (AP) is one of the most researched phenomena in the field of music perception and it is historically considered a rare ability by many musicians, psychologists and other researchers. A broad bibliographic review on AP was conducted in Germano (2015) and we noticed many conceptual problems, including the necessity for standardization regarding not only AP definition, but also regarding how to measure it. It was also observed that Relative Pitch (RP) is much less researched, being academically neglected in favor of AP. In light of these data, we proposed in this research the construction, application, tabulation and analysis of musical tests regarding pitch perception in different tasks: isolated pitches, melodic and harmonic intervals, triads in root position and first inversion. The researched population consisted of 783 undergraduate music students from 7 distinct Brazilian universities. The tests were based on developed construct models and were analyzed within a psychometric approach using Item Response Theory (IRT), Latent Class Analysis (LCA), Regression and Correlation. Seemingly, this is the first project to seek validation of tests that measure the cognitive abilities named AP and RP. Results indicated that the developed tests have validity potential, satisfactorily measuring both latent labelling of pitches and latent identification of interval relations of pitches. Among our main discoveries, we highlight the possibility that AP might not be satisfactorily measured through tasks of labelling isolated pitches without reference, which are commonly found in AP literature. Also, both pitch labelling (regarding AP) and identification of interval relations of pitches (regarding RP) fit better to a dimensional perspective than to a categorical one. (AU) | |
