PSYC23H3 Lecture Notes - Lecture 6: Tonality, Musical Composition, Major Scale
Document Summary
Individuals may disagree about the rate of the tactus: because they extract different perceptual groupings from the musical signal. In discriminating the tempo difference between a swing rhythm from a march rhythm, the jnd is as high as 20% Clara rebello: accents emphasize the beat periodicity itself or certain beats relative to others, some are acoustically marked (i. e. , by differences in the intensity of the sound . Again, rite of spring: others arise from top-down intentions or the expectations of the listener: . Imagining an accent on every second or third tone enhances oscillatory power at the frequency of the imagined meter. Individual musicians must adjust the timing of their movements to subtle errors and asynchronies of other musicians. Identification also occurs when expert listeners identify a favourite performer based entirely on the subtle differences in timing and timbre: beat perception is a universal human capacity, yet there are a few reported cases of beat deafness:
