It has been shown that music has an effect on the brain. This study explored whether listening to music helps concentration. Previous research on the effects of music on brain development and concentration has shown that Baroque music promotes learning because its 60 beats rhythm favours a state of calmness which improves attention. A visual discrimination task was performed under two conditions: control (without music) and assessment (with music: Winter from Vivaldi’s Four Seasons). I hypothesized that performance in the test would improve when listening to music. The statistical analysis of the data proved the hypothesis.
