It's been about a year since I plowed through as many courses here as I could. After that I have just been focused on learning as many songs as possible and not really focusing on technique.
Came back to drink from the well again and see what comes up for me a second round through the courses.
This is where I started, with asking myself how I am doing on my pentatonics, and I can definitely tell a difference. Last year when I started there is no way a basic melody through all the positions would have just come out of me.
