This workshop is designed for people who know how to strum chords but marvel at guitarists who appear to be able to improvise at will; play for hours on end without apparently having to think about it.
It unlocks the technique of improvising. Once you're shown the system you realise immediately that it's nowhere near as hard as it looks.
To be honest, when I first saw people playing lead guitar, I thought I'd never be clever enough to play like them. Then a guitar tutor showed me the technique and unlocked it in just one lesson. I'll be doing the same at Sun and Moon. You just need a guitar and plenty of time to practise.Be sure to bring your own guitar; the festival doesn't provide them.
