This iconic tune, from Bob’s early days, fits in really well the the recent set of lessons on ear training. The way to get started with this is to listen to the version from Bob’s 1965 album Highway 61 Revisited, as well as the later, live version from Self-Portrait, and see what you can hear going on.
In the “Listen” segment I play through the progression in a couple keys, including one time with only bass notes. If you know what chords to look for in a major key, you should be able to figure most of this out without any of the “Clues & Answers” that follow.
There is also a short bit on strumming at the speed of sixteenth notes and tips on the intro.
