Although music and other forms of art can develop in diverse directions, they are linked to the genetic profiles of populations. Hearing music is a strong environmental trigger that serves as an excellent model to study the crosstalk between genes and the environment. We propose that the ability to enjoy and practice music requires musical aptitude, which is a common and innate trait facilitating the enjoyment and practice of music. The innate drive for music can only have arisen by exposure to music, and it develops with motivation and training in musically rich environments. Recent genomic approaches have shown that the genes responsible for inner ear development, auditory pathways and neurocognitive processes may underlay musical aptitude. It is expected that genomic approaches can be applied to musical traits and will reveal new biological mechanisms that affect human evolution, brain function, and civilisation.
