RHYTHM PATTERN PERCEPTION IN MUSIC RHYTHM PATTERN PERCEPTION IN MUSIC: THE ROLE OF HARMONIC ACCENTS IN PERCEPTION OF RHYTHMIC STRUCTURE. By

The application of the label music to complex sound requires structure. Musical or rhythmic structure can be thought of as being due to the interaction of two theoretically distinct structures of phrase and metre. Perception of both metrical and phrase structure is dependent not only on the physical structure of the acoustic presentation but also upon cognitive structure being imposed on the auditory sensations. Early work in the psychology of music focussed on establishing the perceptual cues that determine the parsing of music in time. These perceptual determinants can be categorized on the basis of the theoretical components of music: melody, harmony, rhythm, and timbre. With the exception of accent strength based on stability judgments of tones or chords (i.e., structural accenting), phenomenal accents have been assumed by some theorists to be equally-salient, additive, and categorical. The assumption of equal accent strength not only has been applied to different phenomenal accents within a theoretical component category but also between categories. Three series of experiments were conducted to test the assumption o
