A Perceptual Analysis of Mozart's Piano Sonata K. 282: Segmentation, Tension, and Musical Ideas

Investigations of the psychological representation for musical meter provided evidence for an internalized hierarchy from 3 sources: frequency distributions in musical compositions, goodness-of-fit judgments of temporal patterns in metrical contexts, and memory confusions in discrimination judgments. The frequency with which musical events occurred in different temporal locations differentiates one meter from another and coincides with music-theoretic predictions of accent placement. Goodness-of-fit judgments for events presented in metrical contexts indicated a multileveled hierarchy of relative accent strength, with finer differentiation among hierarchical levels by musically experienced than inexperienced listeners. Memory confusions of temporal patterns in a discrimination task were characterized by the same hierarchy of inferred accent strength. These findings suggest mental representations for structural regularities underlying musical meter that influence perceiving, remembering, and composing music.

In two experiments we addressed the roles of temporal and pitch structures in judgments of melodic phrases. Musical excerpts were rated on how good or complete a phrase they made. In Experiment 1, trials in the temporal condition retained the original temporal pattern but were equitonal; trials in the pitch condition retained the original pitch pattern but were equitemporal; and trials in the melody condition contained both temporal and pitch patterns. In Experiment 2, one pattern (pitch or temporal) was shifted in phase and recombined with the other pattern to create the pitch and temporal conditions. In the melody condition, both patterns were shifted together. In both experiments, ratings in the temporal and pitch conditions were uncorrelated, and the melody condition ratings were accurately predicted by a linear combination of the pitch and temporal condition ratings. These results were consistent across musicians with varying levels of experience.
