How Learning a Musical Instrument Affects the Development of Skills

Despite numerous studies on skill development, we know little about the effects of extracurricular music activities on cognitive and non-cognitive skills. This study examines how music training during childhood and youth affects the development of cognitive skills, school grades, personality, time use and ambition using data from the German Socio-Economic Panel (SOEP). Our findings suggest that adolescents with music training have better school grades, are more conscientious, open and ambitious. These effects are stronger among adolescents from lower socio-economic status. In order to address the non-random selection into playing music, we take into account detailed information on the child and its parents, which may determine both the decision to pursue music lessons and educational outcomes. While lacking truly exogenous variations in music activities, our results are robust to a large range of sensitivity tests. We thereby approach causality better than previous observational studies.
