G4V is an American non-profit organisation dedicated to providing relief to struggling veterans through the healing power of music and the community (G4V, 2019). The organisation was started because the founder, Patrick Nettesheim, a guitar instructor, started working with a Vietnam veteran who found that guitar lessons were appropriate for veterans in allowing self-expression and positive human interaction. A G4V guitar instruction program was developed with the aim of providing struggling veterans with physical injuries, PTS and other emotional problems with a unique therapeutic alternative (G4V, 2019). G4V provide weekly individual lessons so that students can learn at their own pace and monthly group sessions to establish a community atmosphere. Once a student has completed the initial 10 lessons of the programme the student is awarded their own guitar to continue within the groups. In Dillingham (2011), a study with the US Department of Veterans Affairs carried out a 6-week program with 40 US veterans suffering from PTS. The veterans participated in one individual guitar lesson per week and one monthly group guitar session facilitated by experienced instructors in partnership with G4V. The veterans were aged between 22 and 76. According to Dillingham (2011), the results were remarkably successful, showing positive benefits for the 6-week intervention. The primary outcomes included a 21% improvement in PTS symptoms, a 27% reduction in symptoms of depression and a 37% increase in feelings of a better quality of life.
