Nobody attempting seriously and succintly to answer the question here even the article. As far as i understand pattern recognition is basically what the cortex (in all its various divisions) does. Which is basically one of our most important higher functions and what sets mammals apart from other animals intelectually. Recognising a melody is not so different from recognising the voice of a friend or the route to walk home. Except for different input types. Except the fact that music and melody/harmony is not just 'match a pattern' but is designed essentially to tease, test and develop the pattern recognition function by taking simple clear ratios then finding ways to make them a little on edge mathematically in different ways. So we shouldnt find it weird that music can give most of us pleasure itself because its literally the same mecahnism as things that are finding food or a good partner to mate with. Then theres lyrics and the social side of music which puts a whole different twist on it. The above is pure rhythm and pitch only enjoyed individually.
