Art and science

In the TOK class, we have Mr. Jefferson's story for us about his music journey, he studied to play saxophone, but he ended because loneliness, he played the piano. He felt enjoyable to play music. My question was, "Do all pieces of music have a patten to seek?", he had a great answer as conclusion," yes, it is like mathematics to have a calculation to make some piece accurate, but it is more free style than math, math connects to music." , he unraveled my confusion, it's helpful for me to get deep understanding of TOK on music area.
