Efectos de la percepción de dos estilos musicales sobre el nivel y localización de la actividad electroencefalográfica en músicos pertenecientes a contextos culturales occidental e indígena

The study of music has been crucial for the exploration of how the brain modifies through experience. This study explored the type, level, and localization of electroencephalographic activity inaccordion players from different cultural contexts during the musical perception of classic and indigenous musical pieces played in accordion, mapping the brain with electroencephalograms. Theoretical analysis was based on Altenmüller’s musical perception model, according to which it was found that in comparing participants without musical training, in classical and indigenous musiciansmore brain regions activate during perception. In contrast, in the type of electroencephalographic activity it was observed that while rapid activity predominated in classical musicians, the records of indigenous musicians presented negative figures on the rapid activity’s base register, predominance of slow frequencies, and outstanding changes in the amplitude. As explanation, it was considered that slow activity might be associated to more emotional, spiritual, and intuitive representations that indigenous build in music since it has a sacred and ritual connotation and is considered a vehicle of communication between “the symbolic universe and the earthly life”
