Shedding more light on our statement that artistic aptitude in metal is a rare trait, a University of HELLsinki study reveals that musicality is more of an inborn characteristic than most think:

In the study high music test scores were significantly associated with creative functions in music (p< .0001), suggesting composing, improvising and arranging music demands musical aptitude. Creativity is a multifactorial genetic trait involving a complex network made up of a number of genes and environment. Here was shown for the first time that the creative functions in music have a strong genetic component (h2 =.84; composing h2 =.40; arranging h2 =.46; improvising h2 = .62) in Finnish multigenerational families. Additionally the heritability estimates of the musical aptitude were remarkable.

To elucidate the neurobiological basis of music in human evolution and communication the researchers demonstrated an association of arginine vasopressin receptor 1A (AVPR1A) gene variants with musical aptitude. In the previous studies the AVPR1A gene and its homologies have been associated with social, emotional and behavioral traits, including pair bonding and parenting. The results suggest that the neurobiology of music perception and production is related to the pathways affecting intrinsic attachment behavior.

“Music is social communication between individuals,” says Liisa Ukkola. “Darwin proposed that singing is used to attract the opposite sex. Furthermore, lullabies are implied to attach infant to a parent and singing or playing music together may add group cohesion. Thus, it is justified to hypothesize that music perception and creativity in music are linked to the same phenotypic spectrum of human cognitive social skills, like human bonding and altruism both associated with AVPR1A. We have shown for the first time in the molecular level that music perception has an attachment creating impact.”

In more layman terms: ability in music, meaning not just technical skill but creativity and general talent at composing and improvising, is determined mostly by the genes. Not just that, it is also claimed that music making is intimately related with the human traits associated with bonding and communication with other human beings: we use music to transmit to each other ideas so complex that we would be unable to convey with speaking or gestures and do so because we care about communicating those ideas to the world.

All of this data makes one thinks twice about supporting each and every band that comes our way. Not everyone can be an artist and create great, transcendental works, so why should we keep encouraging participation in the metal scene when we can be more concerned about quality and not quantity?
