“…It is assumed that the amplitude of this wave reflects the degree of mismatch between the processed event and the representation in sensory memory of the “expected” event ( Folstein and Van Petten, 2008 ). In our previous studies, we showed that the amplitude of the N200 wave is related to the processing of tonal harmony (the relationship between tones in musical sounds), which along with rhythmic organization refers to the key elements of musical syntax in traditional Western music ( Radchenko et al, 2019 ). This suggests that the N200 wave will also be sensitive to changes in temporal organization, reflecting its representation in sensory auditory memory.…”

Music is increasingly being used as a therapeutic tool in the field of rehabilitation medicine and psychophysiology. One of the main key components of music is its temporal organization. The characteristics of neurocognitive processes during music perception of meter in different tempo variations technique have been studied by using the event-related potentials technique. The study involved 20 volunteers (6 men, the median age of the participants was 23 years). The participants were asked to listen to 4 experimental series that differed in tempo (fast vs. slow) and meter (duple vs. triple). Each series consisted of 625 audio stimuli, 85% of which were organized with a standard metric structure (standard stimulus) while 15% included unexpected accents (deviant stimulus). The results revealed that the type of metric structure influences the detection of the change in stimuli. The analysis showed that the N200 wave occurred significantly faster for stimuli with duple meter and fast tempo and was the slowest for stimuli with triple meter and fast pace.
