The many articles by the same author display similar high scholarship and clear thinking. Another noteworthy book is Ronald J. Sherrof's Discover the Art of Guitar Fingerings. His methodology is not as refined as that of Duncan. However, the work is valuable as a much needed reference source for notation and terminology associated with technique. One of the most difficult and controversial areas of technique lies in the use of the right-hand.
Interpretation is the highest level of technical consciousness.
Interpretation demands the knowing of musical, anatomical and physical properties to determine the very best way to present a piece of music. Most authors advocate the use of musical analysis in determining which techniques will have the most meaningful effect on the music. The technique of practicing is another area receiving excellent contributions. Effective practicing involves a conscious and organized approach to all aspects of performing. The nearest thing to a comprehensive work on this subject is The Art of Practicing, by Alice Artzt.
