I am a guitar tutor and have many tales to tell of the lack of appreciation by the 'establishment' of Traditional music. I recently had a pupil entered into a Young Musicians competition and, despite blowing the competition away with his performance of Davy Graham's 'Angii' he wasn't even placed because he had the temerity to learn the piece by heart and didn't use written music.
Although using different tunings is a good idea, the examiners generally do not understand what is going on, but can't admit it.
The Arts Council of Great Britain view Traditional music as a pastime, not an art form.
There are many books of Traditional Guitar arrangements available. Suggest pjmusic@btinternet.ccom who have a good selection.
