Thought I'd share some of my early experiences with the Van Hemert system. About a year ago I bought the book which includes access to a set of accompanying videos on youtube. I had a flick through the book and it didn't look very convincing or engaging so I threw it onto the growing pile of unused resources... and there it lay forgotten.
Shortly before Christmas I was looking through my stuff looking for inspiration and I picked up the Van Hemert system again. This time I gave it a proper look and resolved to really commit to it and see what happens. That was six weeks ago and in that time I've put a considerable amount of hours into this.
Now it's still early days but this method seems really good! I'm really noticing some progress and I've always got a clear goal to aim for every time I pick up the guitar. Once you've got his fundamental shapes under you fingers it quickly becomes fun.
Hopefully this post will help other struggling improvisers.
