Roy Courtnall Summerfield  is a luthier, author, teacher and lecturer in musical instrument technology, and has worked mainly in the research and making of  the Spanish classical guitar.

He is the author of two books; Making Master Guitars and The Art of Violin Making.
Making Master Guitars is both a practical guide and a historical summary and includes detailed working drawings and plans of guitars by the leading luthiers of the 19th and 20th centuries, including Antonio de Torres, Hermann Hauser, Robert Bouchet, Ignacio Fleta, Santos Hernandez, Hernandez and Aguado, Daniel Friederich and Jose Romanillos. Thus readers are able to make reasonably close replicas of these instruments.

The Art of Violin Making (co-written with the violin maker Chis Johnson, and with a foreword by Lord Yehudi Menuhin), followers a similar format to Making Master Guitars and is closely based on the violin making method taught at the Newark School.

 In 1994 Courtnall was asked by the Newark School of Violin Making in the United Kingdom to write the syllabus and set up a new course in Classical Guitar Making. After an initial intake twelve students, the course rapidly expanded to become the leading vocational course in guitar making in the United Kingdom, awarding a  BA(hons) Musical Instrument Craft qualification through the University of Hull.
