O'Connor has developed a string instrument technique for music teachers and students, The O'Connor Method - A New American School of String Playing.[15] The method places an emphasis on music and playing techniques from North America, in addition to focusing on rhythmic development, ear training, and improvisation.
The method is published as a series of books and also contains short essays about famous American fiddlers such as Thomas Jefferson and Davy Crockett, the history of Gypsy and Mariachi music, and various dances. Teacher training sessions based on the method take place around the United States and in other countries.
