Watch the Highlands online guitar lesson by Jeff McErlain from Soloing the Changes
This tune is called "Highlands", and it's from my record I'm Tired.
It uses one of the most common chord changes in popular music, the I-V-VIm-IV. It shows us how important melody is when composing. We could stick to an E major pentatonic scale on this tune and be fine, in fact I largely do, as I think it works nicely. My CD is available at all fine online locations!
