Guitar Craft (GC) was a series of guitar and personal-development classes, founded and often presented by Robert Fripp, who is best known for his work with the rock band King Crimson. Guitar Craft courses introduced students to new standard tuning and ergonomic playing with the plectrum (pick), often using steel-stringed, acoustic, shallow-body guitars from the Ovation Guitar Company.
By 2011, three thousand students had completed the courses. Students who continue to practise Guitar Craft playing have been called "crafties". Notable crafties include Trey Gunn and the California Guitar Trio (all four of whom, with Fripp, constituted The Robert Fripp String Quintet) and Markus Reuter. Crafties have recorded several albums under the name of "Robert Fripp and the League of Crafty Guitarists", for example.
After 25 years, the Guitar Craft movement transformed its activities into Guitar Circles, which offer introductory courses and performances in Europe and the Americas. Guitar Circles meet in many cities; in particular, The Seattle Guitar Circle meets for practices and performances and also sponsors a school.
