The molecular genetic basis of music ability and music-related phenotypes

In the past decade, researchers have sought to uncover potential genes that underlie various musical traits through molecular genetic approaches once the genetic basis of a musical trait has been established using behavioral genetic methods. Since the 1980s, progress in molecular genetic technology and bioinformatics has brought about the advent of human molecular genetic approaches, especially for elucidating the genetic mechanisms of complex diseases. In contrast, the investigation of the molecular genetic basis of music ability only began to surface in recent years, with Irma Järvelä, a clinical geneticist at the University of Helsinki, Finland, and her collaborators contributing a sizeable and significant research output on this topic. Although this field is still in its infancy, some exciting and converging results are already beginning to emerge
