One of the most interesting aspects of auditory perception is how music affects the brain. The method to analyse music’s influence on the brain’s neuro response is functional near-infrared spectroscopy (fNIRS). This study focuses on examining whether music has a significant impact on brain oxygenation. The study aimed to determine whether there was a noticeable difference in brain oxygenation during listening to music. Ten participants were asked to select two songs: the first that triggers positive emotions and the second that triggers negative emotions. The presented study used the fNIRS (functional Near-Infrared Spectroscopy) method to measure brain oxygenation. An important aspect of the research was observing how oxygen levels change over time while listening to a single song. All such changes should be reflected in the oxygen levels in the brain cortex.
