While I was looking for David’s video of “My Gentle Harp”, I came across his site and David Russell’s Tips for Guitarists which been around for a while, but it took me ages to discover them – they are very simple and wise, and cover a surprising amount of ground with good humour and grounded common sense. I hope you will find these tips from an experienced musician who is also a great artist and human being helpful.
My favourite entries are New Life to the First String and Don’t Sound like a Typewriter!
