# The Mathematics of Music

There is no textbook. All lecture notes will be posted right here. For further information I recommend David Benson's book Music: A Mathematical Offering, which is available for free. The webpage of Daniel A. Russell has a lot of nice animations of acoustic phenomena. My friend Michael O'Connor wrote some great audio demonstrations for this course.
