A new twin study published in Nature Communications provides evidence that how much people enjoy music is partly influenced by genetic factors. Researchers found that over half the variation in people’s sensitivity to musical pleasure can be traced back to genetic differences. These genetic influences appear to be mostly unique to musical enjoyment, rather than being shared with broader reward sensitivity or basic musical skills like pitch or rhythm perception.
Importantly, the researchers found that this genetic influence on musical enjoyment was largely distinct from the genetic influence on music perception abilities or general reward sensitivity. Even after accounting for genes related to basic music skills or general pleasure-seeking behavior, nearly 40% of the variation in music enjoyment could still be traced to genetic factors unique to music enjoyment itself. This supports the idea that music enjoyment is not just a side effect of other brain functions, but a distinct capacity with its own biological foundation.
