John Duarte was the composer of nearly 150 works for the guitar and lute (many commissioned with funds provided by the Arts Council of Great Britain and other sources, official and private, both domestic and overseas). Many have been published and over half have been commercially recorded. He was also the author of very many arrangements (several also recorded) and didactic works.
As the writer of countless articles he was a regular contributor to Soundboard, interviewer and reviewer of books, music, concerts and recordings of many kinds in Gramophone, Music Teacher and Classical Guitar, and author of numerous concert-programme notes and about 250 liner notes for records and CDs of various kinds, including those for the complete reissue of Julian Bream’s recordings for RCA (28 compact discs). He received a GRAMMY Award for his annotation to the reissue of Segovia’s recordings of 1927-39. His Appalachian Dreams op. 121 formed the centrepiece of the 2001 GRAMMY Award-winning album Dreams of a World by Sharon Isbin. The Joan Baez Suite op. 144 was also the centrepiece of her 2010 GRAMMY Award-winning album, Journey to the New World. He contributed regularly to Music in Education, Guitar Review, Guitar International, Music & Musicians, Records and Recording, and Performance and was a contributor to the revised edition of The New Grove Dictionary of Music and Musicians.
