David Walden has been a music educator for over 30 years.

His philosophy of teaching musical theory is to make music enjoyable. To this end he has written Music Theory for the Bored and Confused, Books I & II. Both books are unconventional and represent an imaginative and humourous presentation of musical notational development.
