  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.
