Alternative Conclusion: Humans are very good at spotting patterns and making generalisations. I can identify that certain plants are trees, or certain animals are dogs, even trees or dog breeds I've never encountered before. Most people would agree with my identification. People from a similar cultural background to me will generally agree with me as to whether a completely novel piece of music is in tune and rhythmic (i.e. "grammatical", not necessarily "good"). Music from some traditions often sounds discordant (i.e. "ungrammatical") to me, due to the different scales used, yet I am sure that they must be considered grammatical by those who are familiar with such music.
