The Musical Ear Test: Norms and correlates from a large sample of Canadian undergraduates.

We sought to establish norms and correlates for the Musical Ear Test (MET), an objective test of musical ability. A large sample of undergraduates at a Canadian university (N > 500) took the 20-min test, which provided a Total score as well as separate scores for its Melody and Rhythm subtests. On each trial, listeners judged whether standard and comparison auditory sequences were the same or different. Norms were derived as percentiles, Z-scores, and T-scores. The distribution of scores was approximately normal without floor or ceiling effects. There were no gender differences on either subtest or the total score. As expected, scores on both subtests were correlated with performance on a test of immediate recall for nonmusical auditory stimuli (Digit Span Forward). Moreover, as duration of music training increased, so did performance on both subtests, but starting lessons at a younger age was not predictive of better musical abilities. Listeners who spoke a tone language exhibited enhanced performance on the Melody subtest but not on the Rhythm subtest. The MET appears to have adequate psychometric characteristics that make it suitable for researchers who seek to measure musical abilities objectively.
