Watch the Oregon online guitar lesson by Stephen Bennett from Harp Guitar Repertoire
I can hear the words "I'm going back to Oregon" in the opening phrase of this tune. And so should you hear that in your own playing of this piece. I never wrote lyrics for the whole thing (and probably never will) but still, I think the melody sings. Keep that sense of lyricism in the melody as you learn this.
As I write this text while listening to this performance of Oregon (several months after recording it), it occurs to me that the tempo could be a little slower. Or not, your call.
