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.
I always try to think about melody and it’s never a problem if someone refers to me as a melodic player. I take that as the highest compliment. It’s what people remember. Why were the Beatles songs so successful? Melody.
It was a real revelation when I realized that melodies are made of chord tones, and the best note to play on a chord is one of the notes in that chord. The scale it comes from is important, but not nearly as important as the notes of each chord.
